CNC 7RL Tattoo Needle Cartridges 20-Pack Round Liner Bugpin — 316L Stainless, Sterile Membrane

CNC 7RL Tattoo Needles Cartridge 20-pack are disposable round-liner bugpin cartridges with a secure membrane for clean, precise lining and universal compatibility.

These CNC cartridges combine 316L surgical stainless steel needles with medical-grade plastic housings to deliver consistent, single-use performance. Each cartridge is EO gas sterilized and individually sealed to meet studio hygiene standards. The EN04-20-1007RL set contains 20 round-liner bugpin cartridges (7RL) designed for fine, tight lines and smooth ink flow while preventing backflow into the grip.

How do these 7RL bugpin cartridges improve line work?

The 7RL bugpin configuration tightens the cluster of small-diameter needles to produce crisper, more detailed lines than standard liners. Because the needles are finer and packed closer, artists can achieve sharper edges and delicate hair-stroke effects with less trauma to the skin.

• 7-round bugpin grouping for precise, thin lines
• Fine-point needles reduce skin stretching and overwork
• Consistent needle alignment for even ink deposit

Are these cartridges safe and compatible with my machine?

Each CNC cartridge is EO gas sterilized and individually blister-packed for single use, minimizing contamination risk. The plastic housing fits most rotary tattoo machines and standard cartridge grips, making them a flexible option across different setups.

• 316L stainless steel needles and medical-grade plastic housing
• Individual sterilization and single-use packaging
• Universal fit for the majority of rotary machines and grips

What prevents ink or fluid from entering my grip?

CNC cartridges include an integrated membrane that blocks ink and fluids from traveling back into the grip or machine. An internal stabilizer also minimizes needle wobble, improving control and reducing splash or backflow during use.

• Secure membrane seals the cartridge to stop backflow
• Stabilizer reduces needle play for steadier strokes
• Design lowers the chance of grip contamination and messy cleanup

How many cartridges are included and how are they packaged?

This product ships as a 20-piece set, each cartridge individually sealed after EO gas sterilization. The packaging supports studio workflows by keeping replacements on hand and maintaining hygienic standards between clients.

• 20 individually sealed cartridges per pack
• Single-use disposables to simplify disposal and compliance
• Compact pack size for storage and travel
