What needle types are included and when should I use each?

The assortment contains round liners (RL), round shaders (RS), magnum flats/mixed magnums (M1) and round magnums (RM). Liners are for crisp outlines; shaders are for softer fills and subtle gradients; magnums handle broader color packing and smooth blends.

• 5RL, 7RL, 9RL — precise line work and fine detailing
• 5RS, 7RS, 9RS — small to medium area shading and soft transitions
• 7M1, 15M1 — magnum flats for solid fills, smooth shading
• 7RM, 15RM — stacked magnums for denser color packing and faster coverage

How do these cartridges protect my machine and reduce ink backflow?

Each cartridge includes a high-elasticity rubber membrane designed to block ink and blood from entering the grip and machine. The nozzle’s spiral design helps regulate ink flow while reducing leakage, protecting internal components and making cleanup simpler.

• Elastic rubber plug prevents fluid backflow into the grip
• Spiral nozzle design promotes even ink delivery and reduces drips
• Disposable cartridges eliminate the need for cartridge disassembly and sterilization of internal machine parts

Are these cartridges compatible with my rotary or coil tattoo machine?

The POSEIDON cartridges are produced to standard cartridge dimensions and are compatible with most popular cartridge-ready machines. The universal connection and stable housing fit widely used grips and machine setups, so you can swap cartridges across different devices without adapters in most cases.

• Standardized hub fits common cartridge-ready grips
• PVC housing designed for secure seating and quick changes
• Works with most coil and rotary machines designed for cartridge needles

What safety and quality controls are in place for these needles?

Vidattx supplies each cartridge vacuum-sealed and disinfected prior to packing to maintain sterility until first use. Materials include medical-grade stainless steel for needle points and durable PVC for the cartridge body; manufacturing focuses on consistent sharpness and needle alignment for predictable results.

• Individually vacuum-packed and disinfected cartridges
• Stainless steel needles with consistent sharpness for clean lines
• Durable PVC housing and rubber membrane for safety and performance
