Textured Round Liner Tattoo Cartridges for Bold, Saturated Lines
R&G Bio manufactures textured round liner tattoo cartridges for brands, distributors and studios serving traditional, blackwork and dotwork artists — more ink per pass, fewer dips, factory-direct consistency.
Tiny grooves on the needle taper hold extra ink, so textured needles carry more pigment per dip and lay down bolder, more saturated lines with fewer passes — while the points stay sharp and precision-ground. Sizes 3TRL–18TRL in #10 and #12 gauge.
Every cartridge is EO gas sterilized, batch-coded for full traceability, and produced in ISO Class 7 cleanrooms under an ISO 13485 quality system. Review our certifications and compliance documents and see how we manufacture before you place a bulk order.
We support full OEM/ODM programs — housing colors, private labeling and custom packaging built around your brand, with factory-direct MOQs and tiered wholesale pricing.

Built Like a Medical Device, Priced for Wholesale
Texture only works when it is controlled. Groove depth, point sharpness, and grouping alignment decide whether a textured liner performs or drags. Here is how we control all three.
01 Safety Membrane System
A medical-grade elastic membrane sits inside every cartridge. It keeps needle tension steady during long sessions and stops ink and body fluids from flowing back into the grip and machine. No backflow, no cross-contamination.
02 Micro-Textured Tapers, Sharp Points
We grind the texture into the taper on purpose — controlled micro-grooves, never random roughness. The needle point itself stays sharp and precision-finished, so penetration stays clean while the shaft carries the extra ink.
03 Medical-Grade Housing
The shell is medical-grade polymer with a clear tip. Artists see the ink load while they work. The body has a non-slip grip design, and the standard fitting works with most rotary machines and cartridge grips on the market.C
04 EO Gas Sterilization
Every cartridge is sealed in its own blister pack and sterilized with EO gas. Our sterilization process is validated under ISO 11135, with batch records kept for full traceability.
05 Two-Stage Quality Control
Every unit passes 100% visual inspection on the line. Then 30% of each batch is checked again under 100x microscopy for groove consistency, point sharpness, and grouping alignment. Rough or dull needles never ship.
How Texture Holds More Ink?
A magnum spreads needles across two rows. A flat shader puts them all on one line. That single edge works almost like a blade: it cuts a clean border, fills corners without overflow, and lays down dense, even saturation along the full width of the row. Artists rotate the wrist to work with the flat side for fills, or ride the edge for sharp detail. That is why flat shaders stay in every blackwork, geometric, and traditional artist’s setup — no other configuration gives this level of edge control.
Where Textured Liners Work Best
One series, four core jobs. If the work needs dense, saturated marks in few passes, this is the needle.
Traditional & Neo-Traditional
“Bold will hold.” Textured liners push dense pigment in one pass, so classic outlines stay dark and age well. The go-to choice for old-school and neo-traditional line work.
Dotwork & Stipple
Every dot lands darker and more consistent. The textured surface feeds ink steadily, so stipple gradients and pepper shading build faster with fewer touch-ups.
High-Saturation Black Lines
Lettering, tribal, banners, and heavy blackwork outlines. Large textured groupings like 11TRL to 18TRL lay down maximum-density black lines that stay solid after healing.
Whip Shading & Dark Accents
Fast, punchy whip shading and dense dark accents in black & grey pieces. The extra ink load makes each flick of the needle count — ideal for artists with a confident hand.
Small Group, Fine Bold Lines. Big Group, Maximum Weight.
Needle count sets the line width. Texture sets the density. Match both to the job — that is the whole logic.
3TRL – 5TRL
Fine bold lines, dotwork, small details
7TRL – 9TRL
Everyday bold outlines, lettering
11TRL – 14TRL
Heavy traditional lines, banners
18TRL
Maximum line weight, blackout linework
Textured vs Standard (Polished) Liners
Same grouping, same gauge — different surface finish. That one change controls ink load, needle drag, and which styles the liner serves best.
