Wormhole Tattoo Cartridge Needles 50pcs Assorted Round Liners 3RL–11RL, Anti-Backflow Sterile

These cartridge needles are supplied as a 50-piece assortment designed for tattoo artists who want a selection of round liners on hand. Each cartridge combines a stainless steel needle assembly with a molded disposable housing and a membrane that helps prevent ink from traveling back into the machine. The set includes ten of each size so you can switch between fine, medium and heavier liners during a session without reloading or reshaping needles.

How do these cartridges reduce ink backflow and keep the machine cleaner?

Each cartridge includes a molded rubber membrane and sealed housing that act as a barrier between the needle channel and the machine’s grip tube. This helps reduce the risk of ink migrating into the motor or tubes and simplifies cleanup between clients.

• Rubber-sealed membrane prevents ink from flowing backward
• One-piece disposable housing limits exposure to internal components
• Individual sterile packaging maintains cartridge integrity until use

Which needle sizes are included and what line widths can I expect?

The pack contains ten cartridges each of 3RL, 5RL, 7RL, 9RL and 11RL, covering a range of liner widths for different tattooing tasks. Smaller RLs are suited to delicate fine lines and detail work, while larger RLs deliver bolder lines and faster coverage on outlines.

• 3RL for ultra-fine lines and precise detail
• 5RL & 7RL for standard lining and script work
• 9RL & 11RL for thicker outlines and faster stroke coverage

Are these cartridges compatible with my tattoo machine and do they offer good needle visibility?

The cartridges use a standard shank profile that fits most modern rotary and cartridge-style machines. The translucent light-grey plastic housing improves visibility of the needle cluster so you can see ink flow and needle movement during use.

• Standard cartridge fitting for broad compatibility
• Light-grey tubes enhance needle and ink visibility
• Stainless steel needles paired with durable PVC housing

How are these cartridges packaged and what safety steps are included?

Each cartridge is wrapped and sealed individually to preserve sterility and reduce contamination risk before use. The disposable design eliminates the need to sterilize internal needle components between clients.

• Individually sealed cartridges for single-use convenience
• Pack of 50 with counted assortment for session planning
• Durable materials designed for professional daily use
