Kwadron Tattoo Cartridge Needles 35/7RSLT — 20‑pack Round Shader, Stabilized for Consistent Shading

These cartridges combine a low-friction plastic housing, razor-sharp steel needles and an integrated membrane to deliver dependable shading and blending for professional tattoo artists. Built with Kwadron’s stabilizing system, the 35/7RSLT configuration gives even ink distribution across seven tightly grouped needles while keeping the needle grouping steady in the tip. The single box contains 20 sterile, disposable cartridges suitable for a wide range of shading techniques.

How do these 35/7RSLT cartridges improve shading consistency?

The seven-needle round shader layout produces smooth gradients and even ink laydown when working on midtones and soft shading. The stabilizing system minimizes wobble so strokes remain uniform across skin contours. These design choices reduce the need for repeated passes and help maintain consistent results session after session.
