UPTATSUPPLY Poseidon Tattoo Cartridge Needles, 50pc Mixed Sizes Assortment — Sterile Disposable, Smooth Ink Flow

Designed for tattoo artists who need an all-in-one sterile needle kit, this Poseidon set includes a balanced range of round liners (RL), round shaders (RS), magnums (M1) and curved/round magnums (CM/RM). Each cartridge is EO gas-sterilized and individually blister-packed for hygienic storage and single-use convenience. The needles are stainless steel with a 0.30mm diameter, offering consistent pigment transfer and compatibility with most standard cartridge machines and grips.

Which needle sizes are included in this 50-piece assortment?

This kit contains ten different cartridge types with five pieces of each style, giving you a mix suitable for outlining, shading and filling. The assortment covers small liners through larger magnums so you can switch quickly between detail and coverage.

How do the cartridges perform with ink flow and stability?

Each cartridge uses stainless steel needles and a specially designed tip material to promote steady, predictable ink delivery. The construction reduces splatter and helps maintain consistent saturation while you work.

• 0.30mm needle diameter for controlled line work and shading
• Special tip material that stabilizes needle movement
• Optimized channels for smooth ink flow and minimal clogging

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

Yes — every cartridge in the set is individually blister-packed and sterilized using EO (ethylene oxide) gas to meet single-use hygiene expectations. The one-time joint design supports sanitary practice by eliminating cross-contamination risk when discarded after use.

• Individually sealed blister packs
• EO gas sterilization for each cartridge
• Disposable, single-use design for infection-control workflows

Will these cartridges fit my machine and how do shell sizes relate?

Poseidon cartridges are built to be compatible with most standard cartridge grips and rotary/coil machines. Note that some needle configurations use different shell sizes; the kit matches needle diameter to appropriate shells for optimal performance.

• Works with common cartridge-compatible grips and machines
• 1007RL supplied in 5RL shell; 1009RL in 7RL shell where applicable
• Magnum-to-shell mapping: 1015M1 in 13M1 shell, 1021M1 in 19M1 shell; CM versions follow the same shell logic
