Vidattx Poseidon Tattoo Cartridge Needles 50PCS Assorted Round Liners — Disposable, Membrane-Sealed

Vidattx Poseidon 50PCS Tattoo Cartridge Needles are a mixed-size kit of disposable round liner cartridges (1003RL, 1005RL, 1007RL, 1009RL, 1011RL) designed for consistent ink flow, easy compatibility, and precise line work.

This pack supplies 50 individual, vacuum-sealed disposable cartridges—10 of each round-liner size—so artists can switch between tight lines and bolder outlines without interrupting workflow. Each cartridge combines a stainless-steel needle, a molded PVC housing, and an internal membrane that helps prevent backflow. The nozzle’s spiral-style reservoir improves ink retention and flow, while the cartridges remain compatible with most standardized rotary and coil tattoo machines that accept cartridge-style fittings.

How do these cartridges help me achieve cleaner line work?

The round-liner configurations are engineered for crisp, predictable lines at multiple thicknesses. Needles are grouped and aligned to minimize wobble and give sharper edges for lettering, fine detail, and border work.

• Five liner sizes: 3, 5, 7, 9 and 11-round for varied line widths.
• Stainless-steel needles for consistent sharpness and reduced deflection.
• Precision alignment reduces needle spread and improves control.

Will these cartridges fit my machine and stay hygienic during use?

The Poseidon cartridges are manufactured to a standardized dimension so they snap into most cartridge-compatible tattoo machines. Each unit is vacuum-sealed and sterilized, and an internal membrane reduces accidental ink backflow into the machine.

• Standard cartridge fitting for broad compatibility with cartridge machines.
• Individual vacuum packaging maintains sterility until opened.
• Elastic rubber plug and membrane prevent ink migration into the machine’s grip.

What materials and designs improve ink flow and durability?

Cartridges combine durable PVC housings and medical-grade stainless steel needles for longevity and stability during long sessions. A tapered nozzle with a spiral reservoir stores and channels ink smoothly toward the needle tips for fewer interruptions.

• High-elasticity rubber plug improves the seal and prevents leaks.
• Spiral nozzle reservoir increases temporary ink capacity for steady flow.
• Stainless-steel construction resists bending for consistent performance.

How many cartridges are included and what sizes will I get?

The kit contains 50 cartridges in total—ten cartridges of each round-liner size: 1003RL, 1005RL, 1007RL, 1009RL, and 1011RL. This assortment covers a wide range of line styles from delicate work to thicker outlines.

• 10 × 1003RL (3-round liner) for ultra-fine detail.
• 10 × 1005RL and 1007RL for standard line work and detailing.
• 10 × 1009RL and 1011RL for bolder outlines and shading edges.

Who this kit is for: The Vidattx Poseidon 50PCS cartridge set is designed for professional tattoo artists, apprentices, and hobbyists who want a reliable selection of round liners in one purchase. It suits busy studios that need sealed, ready-to-use cartridges for quick swaps, and learners practicing line consistency without managing single-needle sterilization. If you use cartridge-style machines and want a balanced mix of precise, durable liners with anti-backflow protection, this kit provides an economical and convenient solution.
