BIGWASP Round Liner Tattoo Needle Cartridges, 50pcs Assorted 3RL–11RL, #12 Standard, Sealed Sterile

These are 50 disposable BIGWASP round-liner tattoo needle cartridges in mixed sizes (3RL, 5RL, 7RL, 9RL, 11RL) designed for single-use convenience and broad compatibility.

If you need a ready-to-go supply of round liner cartridges for everyday tattoo work, this assorted pack gives artists a range of common RL options in one sealed set. Each cartridge arrives individually wrapped with a sealed membrane and rubber-band loading to help reduce ink backflow, and the mix covers fine, medium, and larger liners so you can switch quickly between detail and heavier linework without changing brands or machine adapters.

What sizes are included and why does the mix matter?

The pack contains 50 cartridges divided evenly across five RL sizes: 3RL, 5RL, 7RL, 9RL and 11RL. Having multiple liner diameters lets you handle precision outlines, shading edges, and thicker contour lines without reaching for separate kits.

• 10 cartridges each of 1203RL, 1205RL, 1207RL, 1209RL, 1211RL
• Covers common needs from fine detail (3RL) to bold lining (11RL)
• Reduces interruptions during sessions by keeping a graduated set on hand

Will these cartridges work with my tattoo machine?

These BIGWASP cartridges are built to fit most modern rotary tattoo machines and coil setups that accept standard #12 round-liner cartridges. They use the widely adopted #12 standard connection so you won’t need special adapters for most machines used in studios.

• Compatible with standard rotary and coiled machines
• Fits Hawk-style grips and common cartridge-ready setups
• Standardized #12 connection for broad machine compatibility

How do they protect against ink backflow and contamination?

Each cartridge features a plastic membrane barrier and rubber-band loading that help limit ink and fluid moving back into the tube assembly. Single-use, individually sealed packaging keeps each cartridge sterile until opened, supporting hygienic workflow in studio environments.

• Plastic membrane prevents ink backflow into the grip
• Rubber-band loaded needles for consistent tension and placement
• Individually sealed pouches for one-time sterile use

How should I store and handle these disposable cartridges?

Keep cartridges in their sealed pouches until needed, store them in a clean, dry area away from direct sunlight, and discard after single use according to your local biohazard regulations. Avoid opening packages prematurely to maintain sterility and always inspect the cartridge for intact seals before mounting.

• Store at room temperature, away from moisture and sunlight
• Use each cartridge only once and dispose properly
• Check seal integrity and membrane before use

Who is this for: This 50-piece assortment is ideal for professional tattoo artists, apprentices building practice supplies, and studios that require a steady supply of reliable round liners. It’s best suited for artists who use cartridge-ready machines and want a versatile set of sizes for outlines, detail work, and heavier lining without sourcing individual needle counts.
