Yuelong Tattoo Cartridges 40pcs — Mixed 3RL–9RM Sterile Needles with Silicone Membrane for Consistent Ink Flow

Yuelong 40-piece tattoo cartridge set delivers sterilized, mixed round liners, shaders and magnum configurations with silicone membranes for ink control and machine protection.

This cartridge kit gives tattoo artists a ready-to-use assortment of needle configurations—3RL, 5RL, 7RL, 9RL, 7RS, 9RS, 7RM and 9RM—packaged sterile and built from medical-grade materials. Each cartridge features Japanese-standard stainless steel needles inside a polycarbonate shell and a silicone membrane to reduce backflow and noise while improving stability. The design emphasizes consistent ink flow, comfort when handling, and compatibility with most standard rotary and coil grips.

How do these cartridges improve ink flow and line consistency?

The cartridges use a funnel-shaped round-liner tip that stores more pigment near the point and releases it consistently for longer lines. The one-piece needle assembly and neat needle alignment reduce wobble, so lines and dots remain predictable across sessions.

• Funnel-shaped liner head for steady ink storage and release
• Tightly grouped needle alignment for uniform strokes
• One-piece needles for rapid rebound and precise control
• Reduced splatter and fewer interruptions during lining

What safety and sterilization measures are included?

Each cartridge in the set is sterilized with ethylene oxide (E.O.) gas and sealed after production in an aseptic environment. Using medical-grade PC shells and Japanese-standard stainless steel needles lowers contamination risks and improves durability compared with lower-grade materials.

• 100% E.O. gas sterilized and individually packaged
• Aseptic workshop production and sealed packaging
• Medical-grade polycarbonate shell, not PVC
• Clear labeling for traceability and sterile handling

Will these cartridges protect my machine and reduce maintenance?

The silicone membrane prevents ink backflow into the machine, which helps protect internal components and reduces cleaning frequency. The low-noise design and secure tip fit also lower mechanical stress during long sessions.

• Silicone membrane blocks ink backflow into the machine
• Close-mouthed tips for steady strikes and less splashback
• Low operational noise for more comfortable work
• Compatible with most standard grips and tattoo machines

How quickly can I switch configurations while working?

The cartridge system is designed for rapid swaps and easy refilling. Artists can dip into pigment pots or top-fill the cartridge through the upper opening, allowing swift transitions between liners, shaders and magnums during sessions.

• Top-fill opening for quick pigment loading
• Cartridge format enables fast on-the-fly changes
• Assorted pack includes five of each size for uninterrupted workflow
• Funnel liner design reduces the need for frequent reloading

Who is this for: This Yuelong 40-piece mixed cartridge pack is aimed at professional and advanced apprentice tattoo artists who need a versatile, sterilized selection of liners, shaders and magnum cartridges. It suits those using standard rotary or coil grips who want reliable needle alignment, consistent ink delivery, reduced machine contamination and quicker configuration changes during multi-stage tattoos.
