POSEIDON 50-Pack Tattoo Cartridge Needles – 10 Sizes, Universal 0.35 inch Base

A complete, versatile needle kit for professional or home use

The POSEIDON 50-pack delivers a broad range of sterile tattoo cartridge needles in 10 sizes, with 5 needles per size. This variety supports both precise outlines and smooth shading, whether you work in a studio or practice at home. RS-type needles map to Model #12, while all other needles are Model #10, giving you immediate clarity on compatibility and usage across projects. A spiral nozzle design holds 30% more ink than standard needles, and laser-sharp tips aim for crisp lines and clean shading to help you achieve the look you want without sacrificing control.

Crafted with Japanese-grade 316L stainless steel tips brazed to PVC cartridges, each needle undergoes 12 rigorous quality checks to ensure consistent sharpness, durability, and reduced vibration during longer sessions. Expect reliable pigment handling that supports longer bursts of work without a noticeable drop in performance, which may translate to smoother transitions and steadier hand movements over time.
