This assortment covers 5RL, 7RL, 9RL for precise lining; 5RS, 7RS, 9RS for shading and soft gradients; and 7RM, 15RM, 7M1, 15M1 magnums for packing and color saturation. Having multiple configurations in a single set reduces downtime between sessions and lets artists switch quickly for different techniques.

• Round shaders for softer fills and gradients without harsh edges.
• Magnums and mixed magnums for solid fills and smooth color layering.

How do these cartridges manage ink flow and safety?

Each cartridge features a spiral-style nozzle and an elastic rubber membrane that reduces the risk of ink traveling back into the machine. Needles are sterilized and vacuum-sealed to maintain hygiene until opened, supporting safer workflows in busy shops and freelance setups.

• Membrane plug for anti-backflow protection and cleaner machines.
• Spiral nozzle design increases ink capacity and consistent delivery.
• Vacuum-packed and disinfected cartridges for single-use safety.

Will these cartridges fit my tattoo machine and last through sessions?

Needle construction uses stainless steel for lasting sharpness during a session, while the PVC housing offers reliable seating and easy insertion and removal.

• Standardized dimensions for broad machine compatibility.
• Stainless steel needles maintain edge and minimize drag.
• Durable housing ensures secure connection and smooth operation.
