Frequently Asked Questions
Q: What are Round Shader (RS) needles best used for?
A: Round Shader needles are arranged in a circular cluster with slightly more spread than Round Liners, making them ideal for shading, soft blending, color packing, and smooth gradient fills. They're one of the most versatile needle types for both traditional and realism tattoo styles.

A: Yes — these cartridges use a universal design compatible with all standard rotary tattoo pen machines and cartridge-style devices. Always verify your machine accepts standard cartridge sizes before use.
