Wormhole Tattoo Rocket Disposable Cartridge Needles 50pc Mixed Round Liners 3RL–11RL with Finger Ledge for Precise Lining

Wormhole Tattoo Needles Rocket is a 50-piece pack of disposable mixed-size round liner cartridge needles with a finger ledge for improved grip and reliable ink flow.

This set supplies professional and beginner tattooists with ten cartridges each of 3RL, 5RL, 7RL, 9RL and 11RL round liners. Each cartridge is individually sealed, made from PVC and stainless steel, and engineered to reduce backflow and ink leakage. The finger ledge design makes handling easier during detailed lining work and helps maintain steady control across sessions.

What sizes are included and what are they best used for?

The kit contains five round liner sizes commonly used for line work, shading edges, and fine detail. Smaller sizes (3RL, 5RL) are ideal for crisp fine lines; larger sizes (9RL, 11RL) handle thicker lining and bolder outlines.

• 3RL: delicate detail and hairlines
• 5RL: standard lining and small lettering
• 7RL: medium outlines and detail with more ink deposit
• 9RL: bold lines and fast coverage
• 11RL: heavy outlines and thick linework

How does the finger ledge design help during tattoos?

The raised finger ledge gives a tactile stopping point so the artist can hold the cartridge securely without slipping. That extra grip reduces hand fatigue, improves control in tight areas, and helps maintain a consistent needle angle for even lines.

• Prevents slippage during long sessions
• Encourages consistent needle depth and angle
• Improves comfort for repetitive motions
• Compatible with gloved use for hygiene

Are these cartridges safe and compatible with my machine?

Each Wormhole cartridge is sealed and built from medical-grade PVC plus stainless steel needles; they include a rubber plug to prevent ink backflow. They are designed to fit most standard cartridge-compatible rotary and coil tattoo machines for quick swap-and-go use.

• Individually sealed for hygienic storage
• Rubber connector reduces ink backflow
• Universal fit for most cartridge-ready machines
• Durable materials resist bending and corrosion

How should I use and store these disposable cartridges?

Use each cartridge for a single client/session and dispose of it following local biohazard rules. Store unopened cartridges in a cool, dry place away from direct sunlight to preserve the rubber seals and packaging integrity.

• Single-use only — discard after session
• Store sealed at room temperature, low humidity
• Do not autoclave or attempt to sterilize for reuse
• Check seals before use; discard any damaged packaging

This set is suitable for freelance artists, studio professionals, apprentices building their kit, and hobbyists practicing sterile single-use techniques.
