Pack solid pigment quickly and run bold traditional lines with 12G (0.35mm) Round Shader (RS) Cartridge Needles. Featuring standard 0.35mm needles arranged in a parallel round grouping, these cartridges carry maximum ink volume to saturate small areas efficiently without requiring excessive passes.

Choose your preferred cartridge housing style from two trusted studio brands:

• Yilong Diamond: Built with a rigid diamond-profile shell casing that stabilizes needle action, preventing unwanted flex or deflection during dense packing.
