Vidattx Poseidon Tattoo Cartridge Needles 50‑Piece Assorted Round Liners (1203–1211RL) — Sterile Disposable, Anti‑Backflow Spiral

Vidattx Poseidon 50PCS Tattoo Cartridge Needles are a mixed-size kit of disposable round-liner cartridges (1203RL–1211RL) designed to deliver consistent ink flow and precise lines for professional and beginner tattooing.

This 50-piece set includes five round-liner sizes—1203RL, 1205RL, 1207RL, 1209RL, and 1211RL—packaged sterile and ready to use. Each cartridge combines stainless-steel needles with a PVC housing and a high-elasticity rubber plug to reduce backflow. The nozzle’s spiral channel holds more ink for smoother strokes, while consistent manufacturing helps ensure compatibility with most standardized rotary and coil machines.

How do these cartridges improve line work and detail?

The Poseidon round-liners are built for crisp, repeatable lines and controlled ink delivery. Sharpened needle threads and a nozzle that stores extra ink reduce interruptions during outlining and fine work, so artists can maintain stroke consistency.

• Pre-sharpened stainless-steel needles for clean penetration and less drag
• Spiral nozzle design increases ink reservoir and steady flow
• Multiple liner sizes (3–11) for varied line thickness and precision

Will these cartridges fit my tattoo machine?

Vidattx manufactures these cartridges to standardized dimensions to fit the majority of modern cartridge-compatible tattoo machines. The PVC housing and universal plug interface make mounting straightforward, minimizing wobble or misalignment during work.

• Standard cartridge connection compatible with most rotary and coil grips
• Secure rubber plug reduces ink backflow into the machine
• Uniform manufacturing tolerances for predictable fit and needle projection

Are these cartridges sterile and safe to use?

Each needle is disinfected and vacuum-packed to preserve sterility until opened. Materials include medical-grade stainless steel and high-quality PVC; the packaging and design aim to reduce contamination risk and prevent ink leakage during tattooing.

• Individually vacuum-sealed cartridges to maintain sterility
• Hygienic single-use design eliminates cross-contamination
• Spiral nozzle reduces spills and helps protect the machine internals

How long will a cartridge last in a session?

Durability depends on style and coverage, but these cartridges are engineered for extended, comfortable use. Needle construction and stable ink flow let artists work longer without frequent swaps, especially when shading small areas or completing detailed line work.

• Solid needle assembly for consistent performance during long sessions
• Optimized ink retention reduces the need for frequent reloading or swapping
• Suitable for both single-pass outlines and repeated passes when needed

Who this kit is for: The Vidattx Poseidon 50PCS round-liner cartridge set suits professional tattooers who need reliable, varied liner sizes for commissions, as well as apprentices and hobbyists practicing clean lines. It’s ideal when you want a sterile, disposable option that fits most cartridge machines, delivers predictable ink flow, and offers a range of liners for tight detail to medium outlines.
