Vidattx Tattoo Cartridge Needles 50PCS Mixed Sizes 3-11RL — One-Way Membrane & Spiral Nozzle

Vidattx Poseidon 50PCS cartridge needles are a mixed-size set of disposable stainless-steel round liners (3, 5, 7, 9, 11) designed for precise lining, consistent ink flow and universal machine compatibility.

This pack includes 50 vacuum-sealed cartridges — 10 of each round liner size (1203RL, 1205RL, 1207RL, 1209RL, 1211RL) — engineered to help artists maintain sharp lines and steady ink delivery across sessions. Each cartridge features a one-way membrane, spiral nozzle for improved ink holding, and medical-grade materials to reduce backflow and protect your machine. The set is sized for both detailed work and broader lining, giving professionals and learners a balanced kit for everyday tattooing.

Which needle sizes are included and what are they best for?

The bundle contains five round liner sizes: 3RL, 5RL, 7RL, 9RL and 11RL, each in a pack of ten. Smaller sizes (3RL, 5RL) are ideal for fine details and hairlines; mid sizes (7RL, 9RL) work well for outlining and small scripts; 11RL is suited to thicker outlines and bolder linework.

• 1203RL: fine detail, delicate lines
• 1205RL: light lining and small letterwork
• 1207RL & 1209RL: versatile outlining and filling small areas
• 1211RL: bold lines and robust outlines

How does the cartridge design improve ink flow and reduce backflow?

Each Vidattx Poseidon cartridge combines a spiral nozzle and a one-way membrane to manage ink movement and prevent contamination. The spiral tip increases ink-holding capacity while the elastic rubber membrane acts as a barrier against backflow, keeping your machine cleaner and your sessions more reliable.

• Spiral nozzle stores more ink for smoother lines
• One-way membrane prevents ink from returning into the machine
• Elastic rubber plug maintains a secure seal under pressure

Are these cartridges compatible with my tattoo machine?

Vidattx designs these cartridges to match industry-standard cartridge grips and machines. Consistent manufacturing tolerances make them compatible with most cartridge-ready rotary and coil tattoo machines, so you can swap sizes quickly during sessions.

• Standard cartridge connection works with most grips
• Uniform dimensions for predictable fit and performance
• Disposable design for quick changes and safe hygiene

What materials and safety steps are used in production?

The cartridges use medical-grade PVC components and stainless-steel needles assembled under controlled conditions. Each unit is disinfected, vacuum-sealed, and tested to ensure a clean, ready-to-use cartridge straight from the pack.

• Stainless-steel needles for strength and consistent sharpness
• PVC housing with high-elasticity rubber plug for sealing
• Individually vacuum-packed and disinfected for hygiene

Who is this for: The Vidattx Poseidon 50PCS mixed RL kit is for tattoo artists who want a ready assortment of round liners for everyday studio work, apprentices practicing line control, and professionals who need reliable disposable cartridges for fast, hygienic changeovers. It’s well suited for artists who value consistent ink flow, clean machine operation, and a practical mix of sizes for both fine detail and bolder outlines.
