POSEIDON Tattoo Cartridge Needles 50pc Assorted Mixed Sizes — Sterile Disposable Cartridges Compatible with Pen & Grip

POSEIDON 50-piece disposable tattoo cartridge kit supplies a hygienic, mixed assortment of liners, shaders and magnums compatible with standard cartridge grips and pen machines.

This kit bundles 50 individually blistered, EO gas-sterilized cartridge needles in a variety of commonly used configurations so artists can switch sizes quickly during sessions. Built from stainless steel with a stabilized tip material, these cartridges are designed for consistent ink flow and reliable handling across liners (RL), round shaders (RS), magnums (RM) and mixed configurations (M1). The set is aimed at professionals and serious hobbyists who want a range of sizes on hand without compromising sterile packaging or compatibility.

What needle sizes are included and how many of each will I get?

The kit contains ten configurations, five pieces of each for a total of fifty cartridges. Sizes cover fine liners through broader magnums to support outlines, shading and packing.

• 1203RL, 1205RL, 1207RL, 1209RL — round liners for crisp linework
• 1205RS, 1207RS, 1209RS — round shaders for soft shading and gradients
• 1207RM, 1209RM, 1209M1 — magnums and mixed mag for quicker coverage and bold shading

How does the cartridge design affect ink flow and stability?

POSEIDON cartridges use stainless steel needles and a specially engineered tip material to maintain stable performance during use. The construction promotes even ink delivery, which helps reduce blotching and provides smoother results when shading or packing color.

• Stainless steel needles for durability and clean pigment pickup
• Stabilized tip material for steady needle movement and predictable flow
• Disposable membrane to minimize backflow and cross-contamination risk

Are these cartridges compatible with my machine and are they sterile out of the box?

Yes — the cartridges are built to the standard cartridge joint, making them compatible with most cartridge grips and rotary or pen-style machines. Each cartridge is sterilized with ethylene oxide (EO) gas and individually blister-packed for single-use safety.

• Standard cartridge joint fits popular grips and pens
• EO gas sterilization documented on packaging for sterile assurance
• Independent blister packaging for hygienic storage and transport

What should I expect in terms of warranty and returns?
