Kwadron Tattoo Cartridge Needles - Round Shader, Box of 20

The Kwadron Round Shader Cartridges give tattoo artists the grouping consistency and ink flow control needed for clean, predictable shading work. Packed in boxes of 20, these cartridges reduce tip friction and keep needles sharp through a full session, so your performance stays steady from first pass to last.

The Round Shader configuration is purpose-built for filling colour and shading after the contour is laid down. Long taper geometry delivers controlled ink deposit across the full tonal range, making these a strong choice for realism gradations as well as solid colour packing. The cartridges are compatible with most professional cartridge-based machines.

Each cartridge includes a needle stabilisation system that maintains grouping integrity under varying pressure, whether you're working heavy shadow passes or near-dry highlights. A full membrane prevents ink backflow into your machine, keeping your setup clean between clients.

Please select the needle size, diameter, and taper length you require.
