Vidattx Tattoo Cartridge Needles 50PCS Assorted Mixed Sizes — RL RS RM M1, Sterile Disposable with Membrane

Vidattx Poseidon 50PCS cartridge needles are a mixed set of sterile, disposable tattoo cartridges—lined, shading, and magnum sizes—built for consistent ink flow and reliable performance on professional machines.

This assortment gives tattoo artists and ambitious beginners a broad toolkit for linework, shading, and filling without hunting for individual sizes. Each cartridge arrives vacuum-sealed and sterilized, combining stainless-steel needle construction with a molded PVC housing that locks to most standardized rotary and coil cartridge grips. The pack includes multiple configurations so you can switch rapidly between details and large-area fills during a session.

Which needle sizes are included and what are they best for?

The set bundles ten different cartridge types aimed at common studio needs: round liners (RL), round shaders (RS), round magnums (RM) and a mixed mag configuration (M1). Liners are for crisp outlines, shaders soften edges and pack small areas, while magnums speed up color fills and gradients.

• 3RL, 5RL, 7RL, 9RL — fine to bold linework and detail.
• 5RS, 9RS — tight shading and soft texture.
• 9RM, 11RM, 15RM — magnums for efficient color packing and blending.
• 7M1 — mixed mag layout for smoother ink saturation and transitions.

How does the cartridge design help with ink flow and hygiene?

The cartridges use a molded nozzle geometry with a spiral-like channel that helps carry and hold ink near the needle tips for consistent saturation. A rubber membrane seals the back of each cartridge to reduce suck-back and prevent cross-contamination with your machine.

• Spiral-style nozzle improves ink delivery and reduces dripping.
• High-elastic rubber membrane minimizes ink backflow into the machine.
• Individual vacuum-sealed sterile packaging for single-use safety.
• Stainless-steel needles resist corrosion and maintain sharpness.

Will these cartridges fit my tattoo machine and how reliable are they?

These cartridges follow standard dimensions used by most cartridge-compatible rotary and coil grips, making them compatible across major machine brands. Production uniformity and quality control are intended to deliver predictable seating, secure locking, and consistent needle protrusion for repeatable results.

• Standardized cartridge mount works with common cartridge machines and grips.
• Uniform tolerances for consistent needle alignment and depth control.
• Durable PVC housing reduces wobble during high-speed work.
• Pack of 50 ensures enough supply for multiple sessions or clients.

How do these cartridges fit into a tattoo workflow for pros and learners?

The assortment gives professionals a ready range of sizes to handle multi-stage pieces without interrupting workflow to swap specialty needles. For trainees, the variety accelerates learning by letting you experiment with liners, shaders, and mags in real sessions while relying on sterile, single-use cartridges.

• Pre-sterilized, single-use cartridges reduce setup and cleanup time.
• Assortment supports both fine detail and broad fill techniques.
• Simple snap-in connection speeds needle changes mid-session.
• Balanced for both high-control linework and efficient color packing.

Who is this for: Artists who need a versatile, ready-to-use cartridge kit—professional tattooers stocking a studio, apprentice artists building experience, or event operators requiring hygienic single-use supplies. If you value consistent needle performance, convenient compatibility with common cartridge machines, and a variety of configurations in one pack, this 50-piece Vidattx Poseidon set provides practical coverage for many tattoo styles and session demands.
