Vidattx Tattoo Cartridge Needles 50PCS Assorted Round Liners (1003–1011RL) — Membrane & Spiral Nozzle

Vidattx Poseidon 50PCS Tattoo Cartridge Needles are a mixed set of professional disposable round-liner cartridges (10 each of 1003RL, 1005RL, 1007RL, 1009RL, 1011RL) built for precise lining and reliable ink flow.

This cartridge pack gives tattoo artists a ready-to-use assortment of round-liner sizes in a single vacuum-sealed box. Each cartridge uses medical-grade stainless steel needles housed in a durable PVC casing with an anti-backflow membrane and spiral nozzle to stabilize ink flow. The kit is compatible with standard cartridge systems, so it fits most rotary tattoo machines and is suitable for studio sessions, walk-in touch-ups, and practice work.

Which needle sizes are included and when should I use each?

The set contains five round-liner sizes (1003RL, 1005RL, 1007RL, 1009RL, 1011RL), ten cartridges of each. Smaller RL counts (3–5) are ideal for fine detail and delicate linework, while higher counts (7–11) create bolder lines and faster coverage. Having all sizes on hand saves setup time and keeps workflow smooth across different tattoo styles.

• 1003RL: precise micro-lines and script
• 1005RL: small details and thin outlines
• 1007RL: standard outlines and crisp edges
• 1009RL: thicker lines and faster strokes
• 1011RL: bold outlines and filling strokes

How does the cartridge design improve ink flow and safety?

Vidattx cartridges use a spiral nozzle and a built-in membrane to reduce ink backflow and improve fluid delivery to the needle. The spiral shape stores and channels ink more consistently, while the membrane prevents contamination of the machine’s grip and motor. Each cartridge is vacuum-sealed and disinfected before packing to maintain hygiene standards.

• Spiral nozzle enhances consistent ink feed for smoother lines
• Membrane prevents ink backflow into the machine
• Vacuum-sealed packaging for sterile storage and longer shelf life

Are these cartridges compatible with my tattoo machine and safe to use?

These cartridges follow industry-standard dimensions and should fit most cartridge-capable machines without adapters. Materials include medical-grade stainless steel needles and a robust PVC housing to withstand repeated use during sessions. While the cartridges arrive disinfected and sealed, follow your studio’s sterilization and disposal protocols for single-use needles.

• Standard connector fits most cartridge-ready rotary machines
• PVC housing plus stainless steel needles for durability and corrosion resistance
• Single-use, disposable design supports safe, hygienic practice

How do these cartridges help both professionals and beginners?

The curated mix offers flexibility: professionals can switch sizes quickly mid-session, while beginners get a full range for practice and learning line control. The cartridges’ consistent sharpness and reliable ink flow reduce guesswork and make it easier to achieve repeatable results. Plus, the pack quantity keeps studios stocked for multiple appointments.

• Assorted sizes eliminate frequent reordering or mix-ups during sessions
• Consistent needle sharpness aids controlled, repeatable strokes
• Bulk 50-pack supports busy artists and practice routines for learners
