Arrtx Markers: The Most Expensive Median in the Catalogue

Arrtx has the highest median price of any brand measured on this site: $39.99 against a site-wide median of $13.99. It is a 27-listing catalogue built on brush-tip acrylic paint markers, and it holds not a single Amazon's Choice badge. Both of those facts are unusual, and both belong at the top of the page rather than buried.

Arrtx carries 1,620 searches a month across 37 keywords, with arrtx acrylic markers at 1,200 and a keyword difficulty of 0. Its traffic potential of 2,100 is nearly double its own head-term volume, which means the cluster ranks for acrylic queries beyond the brand name. The chemistry that decides all of it is compared at markers for art and drawing.

Twenty-Seven Listings, Sets Only

27 Arrtx products sit in this catalogue. 19 read as acrylic markers by title, five as alcohol markers and one as a fabric marker. Amazon files 19 as Paint Marker, five as Permanent Marker and leaves three unclassified.

Only one listing in the whole catalogue costs under $14, and there are no single-pen replacements. That is the structural reason the median lands at $39.99: every listing is a box. Prices run $13.99 to $144.99 with a quarter above $54.99.

The tip profile is the brand's actual identity. 21 of the 27 listings name a brush tip, six a dual tip, six a fine and three a chisel. A brush nib on a pigment marker is difficult to build and rare to find, and it is the specification Arrtx sells.

Median rating is 4.6, level with the site-wide median rather than above it. 17 listings carry a manufacturer non-toxic claim, one names low odour, and none names an ACMI or AP certification. Not one of the 27 holds an Amazon's Choice badge — the only brand in this batch with zero, against Sharpie's 146 and Arteza's 64.

Where Pigment Lands

The acrylic row is the broadest works row in the grid, and rock painting is the job Arrtx names in its own titles. Stone rates works at 90 searches a month, glass at 460, plastic at 410, chalkboard at 370, metal at 250, wood at 90, paper at 570 and cardboard.

Fabric is conditional at 1,690 searches a month: pigment stiffens the weave and needs heat setting, and one Arrtx listing is sold as a fabric marker on that basis. Ceramic is conditional, because dishwasher survival needs a bake-set range. Whiteboard fails at 100 searches and skin fails at 310.

The five alcohol listings sit in a different row entirely. Alcohol has no works verdict anywhere: paper conditional at 1,820, plastic conditional at 270, metal, ceramic, stone, whiteboard and skin all failing. A buyer moving between the two halves of the Arrtx catalogue is moving between two chemistries with almost nothing in common.

What the Brush Tip Buys and Costs

A brush nib holds more ink at the surface than a bullet or chisel, which is why it lays smoother colour and why it dries out faster when the cap is loose. Both halves of that trade show in the reports.

Drying time at 59% negative is worse than the acrylic type as a whole, which runs at 47% across 18,854 reports and 241 products. That is the brush nib. Value for money at 19% is better than expected for the most expensive median in the catalogue, which says buyers who paid $39.99 mostly felt they got $39.99 of pen.

"Vibrant but they dry out quickly and are very thin and streaky." Arrtx 36 Colors Direct Liquid Ink Acrylic Paint Pens for Rock Painting

"nibs and despite priming attempts the colors are just very weak and not opaque." Arrtx 48 Colors Acrylic Marker, for Rock Painting, Extra Brush Tip

Set those against the opposite report on the same 48-colour listing, and the split is about coats rather than about pens.

"is a coloring sheet by Chet Minton from his Etsy shop, they are very opaque, and if the first layer is not opaque enough, the second layer will." Arrtx 48 Colors Acrylic Marker, for Rock Painting, Extra Brush Tip

Acrylic reaches full opacity in two passes. The site-wide opacity figure is 1,443 reports across 58 products at 42% negative, and Arrtx's own 32% is better than that field average, which supports the two-coat reading rather than a weak-pigment one.

The Skin Tone Set Is the Odd One Out

Arrtx's most-reviewed product is not an acrylic marker at all. The ALP 36 Skin Tone set at $24.99 with 2,184 ratings is an alcohol marker, and the name causes a predictable confusion worth settling: those colours are for drawing skin tones on paper, not for drawing on skin. Alcohol dye is not cosmetic grade, and skin is a flat fail in the alcohol row at 900 searches a month.

"Despite color bleeding (which is expected of alcohol markers), these markers did the job and shaded where I wanted in my drawings." Arrtx Skin Tone Markers, ALP 36 Dual Tip Alcohol Based Art Pen

"a wide range of colors, none of them were dry or scratchy, and they blend nicely. Over all great markers! I just think the brush tips would be better." Arrtx Skin Tone Markers, ALP 36 Dual Tip Alcohol Based Art Pen

That second report is unusual and useful: a buyer who came for the brand's brush tips and got a dual chisel-and-fine format instead. The alcohol line does not carry the specification the acrylic line is known for, and the listing titles are the only place that distinction appears.

Arrtx Leads Nothing, at the Highest Price Here

Acrylic markers go to Posca on 101,361 deduplicated buyer ratings against Arrtx's 19,973 across the entire brand. Alcohol goes to Ohuhu on 137,571. Paint goes to ARTISTRO, permanent to Sharpie, dry erase and wet erase to EXPO, chalk to Chalkola, fabric to Zenacolor, washable to Crayola, dot to Do A Dot Art! and body to BODYMARK.

So a brand at 286% of the field median price, tied with the field on rating, holding no Amazon's Choice badges and leading no category has one argument left, and it is a real one: 21 brush-tip listings. If a brush nib on pigment ink is the requirement — for rock painting, for blended coverage, for anything where a bullet tip leaves visible strokes — Arrtx has the deepest range of it measured here. Outside that, the data points at cheaper, better-rated, more heavily bought alternatives in the same chemistry.

The Rock-Painting Case

Two of the six listings above name rock painting in the title, and stone is the surface where Arrtx's specification makes most sense. A brush nib lays pigment into the texture of a stone in one pass where a bullet tip skips across the high points, and acrylic rates works on stone at 90 searches a month because pigment sits on the surface without soaking in.

The comparison across brands for that job sits at markers for rock, and the chemistry behind every one of them at acrylic markers. What Arrtx brings to it is nib shape rather than ink quality: its opacity rate of 32% negative is better than the site-wide 42%, and its drying rate of 59% is worse than the acrylic average of 47%.

Sealing is the step the reports keep missing. Acrylic on unsealed stone survives handling but not weather, and the matrix note on that cell says weatherproof once sealed. A painted rock left outdoors without a topcoat will fade, and the fade will be filed as a durability complaint against the pen.

What 27 Listings Cannot Tell You

Arrtx carries 19,973 buyer ratings across 27 products, which is 740 per listing. That is enough to trust the brand-level topics quoted above and not enough to compare individual sets against each other with confidence — the 64-colour set at 977 ratings and the 60-colour at 1,040 are within noise of one another.

Two things the data does support. The 4.4-rated 64-colour dual-tip set is the weakest listing in the range and the 4.7-rated 48-colour brush set the strongest, a gap of three tenths that holds across roughly 3,000 combined ratings. And no Arrtx listing holds an Amazon's Choice badge, which for a brand at a $39.99 median is the single most surprising figure on this page.
