OFEYLE Tattoo Cartridge Needles 50PCS Mixed Sizes 3RL–11RM — EO‑Sterilized Disposable Cartridges with Silicone Membrane

OFEYLE 50PCS Tattoo Cartridge Needles are a sterilized, mixed-size set of disposable cartridges (3RL–11RM, liners, shaders, mags) designed for precise, hygienic tattoo work with rotary pen machines.

This kit supplies a professional assortment of 50 individually packaged, EO-sterilized cartridge needles manufactured from 316L stainless steel and fitted with silicone membranes to reduce ink backflow. The translucent housings give clear visibility of ink flow while the needle variety covers common linework, shading, and packing needs. These cartridges are built to be compatible with standard cartridge grips and rotary tattoo pen machines, offering convenience and consistent performance session after session.

What sizes and needle configurations are included in this 50-piece set?

The set includes 10 different cartridge types commonly used by tattoo artists: round liners, round shaders, magnums, and round magnums in multiple sizes. Each size comes with five cartridges to give a balanced supply for a range of techniques and projects.

• 5 × 3RL, 5 × 5RL, 5 × 7RL, 5 × 9RL (round liners)
• 5 × 5RS, 5 × 7RS, 5 × 9RS (round shaders)
• 5 × 9RM, 5 × 11RM (round magnums)
• 5 × 7M1 (standard magnum)

How do these cartridges help keep a tattoo session clean and controlled?

Each cartridge is individually sealed and sterilized with ethylene oxide (EO) gas, reducing contamination risk and saving prep time. A silicone membrane in the cartridge blocks ink backflow, helping protect the machine and maintain hygienic conditions during shading and lining.

• Individually EO-sterilized cartridges ready for immediate use
• Silicone membrane reduces ink backflow and device contamination
• Translucent shell allows monitoring of ink movement during work

Will these needles work with my rotary tattoo pen machine?

OFEYLE cartridges are built to fit most standard cartridge-compatible grips and rotary pen machines on the market. The 316L stainless steel needle construction and common cartridge mounting ensure physical compatibility and consistent needle action for various machines.

• Standard cartridge connection fits most grips and pens
• 316L stainless steel needles for strength and longevity
• Designed for smooth, predictable needle travel and pigment flow

How do these different needle types affect linework, shading, and color packing?

The assortment covers the main functional groups: liners for crisp outlines, shaders for softer filling and gradients, and magnums for dense packing and smooth blends. Choosing the right configuration helps control ink saturation, stroke appearance, and healing behavior.

• Round Liners (RL): tight groupings for fine, consistent lines
• Round Shaders (RS): looser grouping for soft shading and blending
• Magnums (M1, RM): stacked or round mags for efficient color packing and smooth gradients

Who is this for? Tattoo professionals, apprentices, and serious hobbyists who need a versatile, sterile cartridge selection for daily sessions will find this kit useful. It’s ideal for artists who value visible ink flow, anti-backflow protection, and a ready mix of liners, shaders, and magnums to cover client work without frequent restocking. These cartridges provide a practical balance of sizes and types to handle portrait work, traditional pieces, lettering, and color packing while keeping hygiene and machine protection in mind.
