Round Shader Cartridges are used to fill and shade the tattoo after the contour has been made. The needles are arranged along the circumference of the circle, parallel to each other. This is the main difference between Round Shader and Round Liners, where the needles are also arranged along the circumference of the circle, but clustered into a point. With the right spaces between the needles, they provide the perfect ink flow needed for shading and creating tonal transitions. The Kwadron Round Shader guarantees perfect ink injection under the skin.  

One of the fundamental factors that led to the creation of Kwadron cartridges was the desire to provide a product with the highest utility and, above all, the highest quality unattainable by other brands. Using expertise and experience, following trends and listening to tattoo artists, we have created cartridges perfectly tailored to the needs of our customers.
