Box of 20 Metrix Signature Needle Cartridges - Round Shader Medium Taper

The Metrix Signature Needle Cartridges are suitable for artists who specialise in fine line work and PMU treatments, delivering exceptional precision, control, and consistency with every pass. Whether you're creating delicate hair strokes, crisp eyeliner, or ultra-fine tattoo lines, these cartridges provide the accuracy and stability needed for detailed work.

The advanced stabilisation system features multi-point rail guides, optimised membrane tension, and precision-shaped needles to minimise movement and eliminate wobble. This results in ultra-smooth ink flow, enhanced accuracy, and reduced skin trauma making them ideal for PMU procedures. A refined air intake system further supports consistent, uninterrupted ink delivery while helping to prevent clogging.

Designed using premium Japanese Nippon steel and high-quality medical-grade plastic, each cartridge is built for superior sharpness, hygiene, and durability. Strict quality control ensures every cartridge delivers safe, reliable, and consistent performance.

Round Shaders are designed for controlled, smooth shading and densely packed colour, making them ideal for smaller areas, soft blends, and precision work in detailed tattooing and PMU applications.
