Killer Ink Precision Needle Cartridges - Round Liners, Box of 20

Consistent line work starts with a cartridge you can trust not to wobble mid-session. The Killer Ink Precision Needle Cartridges in Round Liner configuration deliver stable, accurate lines from 304 surgical stainless steel needles, each one individually inspected before leaving the factory. Sold in boxes of 20, they give you dependable results at a price point that makes sense when you're buying in volume.

Each cartridge features a fully transparent, smooth contoured tip that gives you clear visibility of the needle grouping as you work. A secure internal membrane prevents any backflow of ink or blood into the grip, maintaining hygiene throughout long sessions - even on high-stroke machines where cheaper membranes tend to fail.

The universal connection fits the vast majority of cartridge-compatible machines. Colour-coded housing makes it easy to distinguish Round Liners from other configurations in the Precision range at a glance, speeding up mid-session swaps when you're running multiple groupings.
