STIGMA Tattoo Cartridge Needles 50pc Assorted 0.35mm RL/RM — Sterile, Precision Lining & Shading

STIGMA Aquamarine Knight EN02B disposable cartridge needles are a sterilized, artist-designed kit of 50 cartridges in assorted round liner and round magnum configurations for precise, professional tattoo work.

These Aquamarine Knight cartridges pair a translucent light-blue housing with surgical-grade stainless steel needles and a built-in membrane to help prevent ink backflow. The set includes five popular configurations—1203RL, 1205RL, 1207RL, 1209RM, and 1215RM—packaged EO-sterilized and ready for standard cartridge-style machines. This kit is built to give tattoo artists consistent performance for lining, shading, and detail work while keeping hygiene and convenience front of mind.

What sizes and needle types are included in this 50-piece kit?

The kit contains five needle configurations, ten cartridges of each, for balanced coverage across common tattoo techniques. Every cartridge uses 0.35mm needle wire for controlled ink flow and consistent groups.

• 1203RL — 3-needle round liner for tight, crisp lines
• 1205RL — 5-needle round liner suitable for medium lines and small details
• 1207RL — 7-needle round liner for bolder lining and small fills
• 1209RM — 9-needle round magnum for soft shading and gradients
• 1215RM — 15-needle round magnum for broader shading and packing color

How do these cartridges protect against ink backflow and contamination?

Each cartridge includes an internal rubber ring and a plastic membrane barrier to reduce the risk of ink or fluid travelling back into the machine. The components are manufactured from medical-grade plastic and 304 stainless steel, then EO-sterilized and blister-packed for single-use safety.

• Plastic membrane prevents ink backflow into the tube
• Rubber ring stabilizes needle group and reduces splash
• EO sterilization ensures sterile out-of-box use
• Single-use disposables reduce cross-contamination risk

Will these cartridges fit my machine and how do they perform in use?

STIGMA Aquamarine Knight EN02B cartridges are designed for compatibility with most standard cartridge tattoo machines and grips. The 0.35mm needle diameter and engineered tip profiles give predictable ink saturation, making them reliable for lining, shading, and color packing.

• Standard cartridge connection fits most clip cord and rotary machines
• Slope-designed round tips for crisp detail; arc-designed flat tips for smooth shading
• Transparent housing helps monitor ink and needle movement
• Consistent pre-set needle groups reduce setup time

What materials are used and how are these cartridges packaged?

The needles are crafted from 304 surgical stainless steel while the cartridge bodies are molded from medical-grade plastic. Each cartridge is EO-sterilized and sealed in an individual blister pack to maintain sterility until opened.

• 304 surgical stainless steel needles for corrosion resistance
• Medical-grade plastic housing for durability and clarity
• Individual blister packs maintain sterile condition
• Pack includes ten of each size for 50 total cartridges
