POSEIDON Tattoo Cartridge Needles 50pc Mixed Assortment — Sterile 10 Sizes for Liners, Shaders & Mags

Poseidon 50-piece sterile tattoo cartridge kit: a mixed set of disposable round liners, round shaders, mags and curved/round mags compatible with standard cartridge grips and machines.

This curated assortment from POSEIDON gives tattoo artists a ready-to-use selection of 50 EO-sterilized cartridges in 10 commonly used sizes. Each cartridge uses stainless steel needles and a single-use membrane design to help maintain hygienic standards, ensure steady ink flow and simplify setup. The set includes liners, shaders and mag configurations suitable for outlining, shading and color packing in a variety of styles and scales.

Which needle sizes and configurations are included?

The kit contains ten sizes with five cartridges of each size for a total of 50 pieces. It covers common liner, shader and mag groupings so you can switch quickly between fine lines and broader fills without changing brands or fittings.

• 1203RL, 1205RL, 1207RL, 1209RL — round liners for crisp outlines
• 1205RS, 1207RS, 1209RS — round shaders for soft blending and detail
• 1207RM, 1209RM, 1209M1 — round mag and round mag 1 for packing and smooth gradients
• Each cartridge is EO gas sterilized and individually blister-packed for hygiene

How do these cartridges perform with ink flow and stability?

POSEIDON cartridges use stainless steel needles and a purpose-built tip material to promote consistent ink delivery and stable needle behavior. The integrated membrane helps prevent backflow while preserving a reliable channel for pigment during long sessions.

• Stainless steel needles designed for smooth pigment uptake and release
• Special tip material for steady needle movement and reduced vibration
• Single-use membrane reduces risk of ink backflow into the grip
• Compatible with standard cartridge grips and rotary or pen-style machines

Are these cartridges safe and ready to use out of the package?

Yes — every cartridge is sterilized with EO gas and individually sealed in a blister pack. Open only when ready to use and dispose of after a single client to follow standard infection-control practices.

• Individually blister-packed and EO gas sterilized
• Single-use, disposable design for one-client use
• Store sealed cartridges in a clean, dry area until needed
• Follow local regulations for sharps and biohazard disposal

Who this kit is for: This 50-piece mixed cartridge pack is aimed at professional and serious apprentice tattoo artists who want a versatile, hygienic starter supply for outlines, shading and filling. It suits studios that need a range of sizes on hand for walk-ins, conventions or long sessions, as well as artists transitioning to cartridge systems who require consistent fit with standard grips and machines.

Key practical points: the collection emphasizes convenience and compatibility — five cartridges per size reduce mid-session swaps, the stainless steel needles encourage smooth ink work, and EO sterilization plus single-use membranes support clinic-level hygiene.
