Arrtx has positioned itself as one of the most aggressive challengers in the budget alcohol marker space. Where Ohuhu built its reputation on sheer value (maximum colors for minimum price), Arrtx has taken a different approach: competing on quality. Their marketing leans heavily on brush nib feel, ink consistency, and artist endorsements — promising a near-professional experience at a budget price.
Bold claims deserve honest testing. We’ve been using Arrtx OROS markers (the brand’s flagship line) for several months across a variety of illustration projects, and this review gives you the unfiltered truth about what they do well, where they fall short, and whether they deserve a place in your toolkit.
The Arrtx OROS Lineup
The OROS series is Arrtx’s main offering and the one we recommend evaluating. It’s available in several set sizes:
| Set | Colors | Approximate Price | Price Per Marker |
|---|---|---|---|
| OROS 40 | 40 | $22–$28 | ~$0.60 |
| OROS 60 | 60 | $30–$40 | ~$0.55 |
| OROS 80 | 80 | $38–$50 | ~$0.52 |
| OROS 90 | 90 | $42–$55 | ~$0.52 |
| OROS 120 | 120 | $55–$70 | ~$0.50 |
| OROS 180 | 180 | $80–$110 | ~$0.50 |
There are also specialty sets focused on specific palettes — skin tones, architectural grays, botanical greens — which is a smart curation approach that shows Arrtx understands how artists actually work.
Arrtx also makes the ALP (Acrylic-Like Pigment) series, which is a more basic line. This review focuses on the OROS, which is the brand’s premium product and the one most worth evaluating.
First Impressions: Packaging and Presentation
Arrtx makes an excellent first impression. The OROS markers arrive in a sturdy carrying case with elastic loops for each marker, organized by color family. The case zips closed and has a comfortable handle. For artists who like organized storage and portability, this is a genuine advantage over competitors who ship markers loose in cardboard boxes.
The markers themselves look professional. The barrel is a matte gray with color-coded caps and clearly printed color numbers. The cap color matches the ink color reasonably well — not perfectly (cap colors are inherently approximate), but close enough to be useful for quick selection.
Each marker is dual-tipped: a flexible brush nib on one end and a chisel nib on the other. The caps snap on securely with a satisfying click.
The Brush Nib: Arrtx’s Strongest Asset
Let’s start with what Arrtx does best, because it genuinely impressed us.
The OROS brush nib is excellent. Not «excellent for a budget marker» — just excellent. It’s a synthetic fiber brush that’s flexible, responsive, and capable of genuine calligraphic variation. Light pressure produces a fine line suitable for detail work and outlines. Moderate pressure gives you a medium stroke for general coloring. Heavy pressure spreads the brush to a broad stroke for filling.
The flexibility is comparable to — and some artists argue superior to — the Ohuhu Honolulu brush nib. It’s slightly stiffer than the Copic Sketch’s legendary Super Brush nib, but the gap is smaller than the price difference suggests.
In extended drawing sessions (2+ hours), the brush nib maintained its shape and point. There was no splaying, fraying, or loss of responsiveness. We’ve seen Ohuhu brush nibs start to soften after similar sessions, so Arrtx earns a durability point here.
Brush Nib Comparison
| Property | Arrtx OROS | Ohuhu Honolulu | Copic Sketch |
|---|---|---|---|
| Flexibility | Very Good | Good | Excellent |
| Fine line quality | Very Good | Good | Excellent |
| Pressure response | Very Good | Good | Excellent |
| Durability | Very Good | Good | Excellent |
| Overall feel | Close to Copic | Functional | The benchmark |
If brush nib quality is your primary concern and you can’t afford Copic, Arrtx is the budget brand to choose.
Ink Quality: Good, With Caveats
Saturation and Vibrancy
Arrtx OROS inks are more saturated than Ohuhu’s. The colors are punchy, vivid, and photograph well. Blues, reds, and greens are particularly strong — they have an intensity that reads well even in photographs and scans.
This higher saturation is a double-edged sword. For bold illustration, pop art, and vibrant character work, it’s an advantage. For subtle, naturalistic work (realistic skin tones, muted landscapes, delicate gradients), the intensity can be overpowering. We found ourselves wishing for lighter, more nuanced tint options in the skin tone range — the lightest skin tones in the OROS set are still quite vivid compared to Copic’s delicate E-series.
Consistency
Ink flow from the OROS markers is consistent and predictable. We didn’t encounter any dry markers, flooded markers, or significant flow variation within our test set (OROS 80). The ink deposits evenly through both the brush and chisel nibs.
Cross-batch consistency is harder to verify without buying multiple sets at different times. Based on our single set plus reports from other reviewers, Arrtx’s consistency appears comparable to Ohuhu’s — generally good, with occasional minor color variations between production runs. Neither brand matches Copic’s near-perfect batch-to-batch consistency.
Blending
Blending is where the nuance lies. Arrtx OROS markers blend well within the same color family. Two adjacent blues, for example, merge smoothly with back-and-forth strokes. The working time (how long the ink stays manipulable before drying) is adequate for two-color blends and usually sufficient for three-color blends.
Where we noticed limitations:
- Cross-family blending (e.g., blue into purple, or yellow into green) is slightly less smooth than Copic. The transition shows more visible stepping.
- Large-area flat fills occasionally show overlap marks where you go back over a dried edge. Working quickly and maintaining a wet edge minimizes this, but it requires more conscious technique than Copic.
- Colorless blender performance is decent but not exceptional. The included blender marker pushes color around but doesn’t create the effortless, airbrushed gradients that Copic’s Colorless Blender produces.
Lightfastness
Arrtx does not publish comprehensive lightfastness ratings for the OROS line, which is a transparency issue. Our informal testing (exposing swatches to indirect sunlight for 8 weeks) showed moderate fading in reds and purples, minimal fading in blues and greens, and no noticeable fading in earth tones and grays.
For artwork that will be displayed under room lighting or direct sunlight, this is a concern. For artwork that’s scanned, photographed, or kept in a sketchbook, it’s irrelevant.
The Chisel Nib: Serviceable
The chisel nib on the opposite end is functional and unremarkable. It lays down broad, flat strokes suitable for filling large areas and creating straight edges. The edge precision is adequate — not as crisp as Copic’s Medium Broad, but comparable to Ohuhu’s chisel.
Most artists who choose the OROS will use the brush nib 90% of the time. The chisel is there when you need it, and it works, but it’s not a differentiating feature.
Color System and Organization
Numbering System
Arrtx uses a letter-number code system similar to Copic and Ohuhu:
- Letters indicate color family (B = Blue, R = Red, YG = Yellow-Green, etc.)
- Numbers indicate saturation and brightness
The system is logical and learnable. Finding complementary colors and blending groups is straightforward once you understand the convention. Arrtx provides a color chart with their sets, which helps with initial navigation.
Color Selection
The 180-color full range covers most color families adequately. Strengths include:
- Grays: A solid selection of warm, cool, and neutral grays in multiple values
- Blues and greens: Rich variety with good tonal range
- Earth tones: Decent coverage of browns, ochres, and siennas
Weaknesses include:
- Skin tones: The range is narrower than Copic’s, and the lightest tints are still quite saturated
- Pastel/light colors: Generally less variety in light tints compared to Copic
- Specialty colors: Fewer unique or unusual colors in the purple-violet and warm-cool transition spaces
Specialty Sets
Arrtx’s specialty sets are a smart product strategy. Rather than requiring you to buy the full 180-color set, they offer curated sets for specific use cases:
- Skin Tone Set (36 colors): Covers a range of skin tones from light to dark. Useful, though we’d want more light tint variety.
- Gray Tone Set (36 colors): Comprehensive grays for architectural, industrial, and monochromatic work. Well-curated.
- Botanical Set: Greens, earth tones, and floral colors for nature illustration.
These specialty sets show that someone at Arrtx understands artist workflows, and they’re a good way to build a targeted palette without buying colors you’ll never use.
Build Quality and Longevity
Barrel and Cap
The barrel is well-constructed from opaque gray plastic. It’s round with a slight ergonomic contour that makes it comfortable to hold. The diameter is slightly wider than Copic Sketch but narrower than some Ohuhu models.
Caps fit securely and seal well. After three months of regular use, none of our test markers showed signs of drying out when properly capped. This suggests the cap seal is effective, though long-term storage performance (12+ months) remains to be verified.
Ink Capacity
Arrtx doesn’t publish ink capacity figures, but based on our usage, the OROS markers appear to hold a similar amount of ink to Ohuhu markers. Heavy users should expect 3–6 months of life from frequently used colors before they start running thin.
Refillability
The OROS markers are not refillable. This is the standard limitation of all budget alcohol markers and the single biggest long-term cost disadvantage compared to Copic. When an OROS marker runs out, you buy a new one. Ohuhu vs Copic comparison
Arrtx does sell some individual marker colors through their website and Amazon, but availability of specific colors can be inconsistent. If your favorite skin tone or go-to gray runs out, you might need to wait for restocking.
Real-World Testing
Portrait Test
We drew a female portrait with skin tones, hair, and a simple background. The brush nib performed beautifully for hair strands and facial features. Skin tone blending was good but required more effort than Copic to achieve smooth transitions — the higher saturation of the lightest tones was the main challenge. We needed to work more carefully with the blender marker to soften transitions.
Result: Very good. Not professional-grade, but impressive for the price.
Manga Character Test
A full-body manga character with flat colors, dramatic shading, and bold lines. This is the OROS’s sweet spot — the vibrant colors, responsive brush nib, and good in-family blending produced a result that would be perfectly at home in a fan art portfolio or social media post.
Result: Excellent. This is where Arrtx markers shine brightest.
Landscape Test
A simple landscape with sky gradient, distant mountains, foreground grass, and a tree. The sky gradient (three-color blend) was the most challenging element. The result was acceptable but showed visible stepping between colors — a limitation we noted in the blending section. The foreground textures (grass, bark) were easy to render with the responsive brush nib.
Result: Good. The sky gradient was the weak point; foreground detail work was strong.
Speed Sketch Test
A 15-minute timed sketch to test how the markers perform under time pressure. The OROS performed well — good ink flow, responsive nib, and adequate blending speed. The markers kept up with a fast working pace without flooding, drying, or lagging.
Result: Very good. The markers don’t slow you down.
Arrtx vs. Ohuhu: Budget Brand Battle
Since both brands compete in the same price tier, this comparison is inevitable.
| Feature | Arrtx OROS | Ohuhu Honolulu |
|---|---|---|
| Brush nib quality | Very Good (superior) | Good |
| Ink saturation | Higher | Moderate |
| Blending | Very Good | Good |
| Color range | 180 colors | 320 colors |
| Price per marker | ~$0.50 | ~$0.45 |
| Specialty sets | Yes (several) | Yes (fewer) |
| Carrying case | Zippered, organized | Varies by set |
| Individual sales | Limited availability | Limited availability |
| Skin tones | Decent | Good |

Final Verdict
Arrtx OROS markers are genuinely good. Not «good for cheap markers» with an asterisk — genuinely good tools that produce professional-looking results in the right hands. The brush nib is the star of the show and is, in our testing, the best budget brush nib currently available. The ink quality is solid, the color selection is thoughtful, and the packaging is surprisingly premium.
The limitations are real but expected at this price point: no refillability, unverified lightfastness, slightly less nuanced blending than Copic, and saturated colors that can overpower subtle work. These are the trade-offs of every budget alcohol marker, and Arrtx manages them better than most.
At roughly $0.50 per marker, the value proposition is compelling. Whether you’re buying your first set of serious art markers or supplementing an existing collection with budget options for practice and experimental work, Arrtx OROS deserves serious consideration.
Overall rating: 4 out of 5 stars. The best budget brush-nib alcohol markers on the market in 2026.
Frequently Asked Questions
Are Arrtx markers as good as Copic?
No, but they’re closer than their price suggests. Copic markers are superior in blending quality, ink consistency, lightfastness, refillability, nib replacement, and batch-to-batch color matching. Arrtx closes about 70–75% of the gap at roughly 7% of the price. For hobbyists and students, Arrtx provides a very satisfying experience. For professionals who depend on absolute consistency and archival quality, Copic remains the standard. Ohuhu vs Copic comparison
Can I buy individual Arrtx markers to replace used-up colors?
Arrtx sells some individual colors through their website and Amazon, but availability is inconsistent. Popular colors may be in stock, while niche colors might require buying a set that includes them. This is a common limitation of budget marker brands. If you use specific colors heavily, check availability before committing to Arrtx as your primary system.
Do Arrtx markers bleed through paper?
Like all alcohol markers, Arrtx OROS will bleed through thin, absorbent paper. On proper marker paper (like Canson XL Marker pad) or bristol board, bleed-through is minimal to nonexistent. Always use paper rated for alcohol markers and put a scrap sheet underneath for protection. How to choose paper for markers
How long do Arrtx markers last?
With moderate use (drawing 2–3 times per week for hour-long sessions), most Arrtx OROS markers will last 4–8 months before the ink runs thin. Frequently used colors (skin tones, popular grays, black) will deplete faster. Since the markers aren’t refillable, depleted markers must be replaced entirely. The carrying case and marker bodies are durable enough to survive regular use for years — it’s the ink that’s the limiting factor.
Are Arrtx OROS markers good for adult coloring books?
Yes, they’re excellent for adult coloring books. The responsive brush nib handles both fine details and broad fills, the vibrant colors look striking on the page, and the blending capability allows for impressive shading and gradients. The main consideration is paper quality — most coloring book pages are thin and will experience bleed-through. Place a sheet of scrap paper behind each page you’re coloring, or choose coloring books with thick, marker-friendly pages.
