Wormhole Tattoo Cartridge Needles 50pc Mixed Sizes 3RL–11RL Disposable Round Liners, Anti-Backflow

Wormhole Tattoo Cartridge Needles are a 50-piece set of disposable round liner cartridges (3RL, 5RL, 7RL, 9RL, 11RL) designed for pen-style tattoo machines and permanent makeup work. These cartridges give tattoo artists a ready-to-use selection of commonly used liner sizes in one pack. Each size comes in groups of ten, packed individually to preserve sterility and assembled with corrosion-resistant stainless steel needles in transparent housings. The set emphasizes compatibility, anti-backflow safety, and a smooth needle action to help you produce consistent lines across skin tones and projects.

What needle sizes are included and how do I choose the right one?

The kit contains five round-liner (RL) sizes: 3RL, 5RL, 7RL, 9RL, and 11RL, ten cartridges of each size. Smaller RLs (3RL–5RL) are best for tight detail and fine lines, while larger RLs (9RL–11RL) cover bolder lining and quicker outlining.

• 3RL: ultra-fine detail, crisp single-line work
• 5RL–7RL: general lining, shading edges, medium detail
• 9RL–11RL: bold outlines, faster coverage, heavy line work

How does the anti-backflow design protect my equipment and clients?

Each cartridge uses a soft-glue internal barrier that reduces the chance of inks or bodily fluids being drawn back into the pen motor. This added defense helps keep the machine cleaner and decreases contamination risk during long sessions.

• Soft-glue backflow barrier blocks pigment and fluids
• Individually sealed bags maintain sterility before use
• Reduces cleaning frequency and protects motor internals

Will these cartridges fit my tattoo pen and how easy are they to install?

Wormhole cartridges are manufactured to a standard cartridge size to ensure wide compatibility with most cartridge grips and pen-style machines. Assembly is straightforward: align, insert, and twist to lock, allowing quick swaps during sessions.

• Standardized fit works with most pen grips and machines
• Transparent housing simplifies needle positioning and ink flow checks
• Quick-twist attachment for fast cartridge changes

What materials and build features affect performance?

The needles are crafted from stainless steel and set in a PVC housing that delivers stable alignment and smooth action. The sleeker, low-tension construction promotes faster retraction and a more consistent needle stroke, which can help artists maintain steady lines with less resistance.

• Medical-grade stainless steel needles for durability and sharpness
• PVC transparent housing for visibility and reliable needle pressure
• Smoother linear action reduces drag and improves flow

Who is this for This 50-piece Wormhole cartridge set is tailored for professional and apprentice tattoo artists, permanent makeup practitioners, and studio owners who need a dependable range of liners on hand. It’s also useful for freelance artists who want a compact, versatile kit that covers fine detail to bold lining while prioritizing hygiene and machine protection.
