An inner membrane within each cartridge prevents ink spit-back, contributing to smoother lines and reducing the risk of clogs. This anti-backflow design enhances both hygiene and performance.

The precise silicone hardness control helps reduce skin lesions and protects the tattoo machine's motor by preventing added load, ensuring a comfortable and safe tattooing experience.
4. Maintenance and Disposal
