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.  

The size of the needles in the cartridge affects the shading and the final result. The SMALLER the needle diameter, the smaller the pixel will be, the softer the overall shading will be, whereas larger needle diameters like 0.35mm (#12) will result in a thicker pixel and stronger shading with a more pronounced texture. Kwadron Round Shader 0.35 mm (#12) comes in variants from 3 up to 18 needles per cartridge, so that you can match the right cartridge to the tattoo you are applying and the desired final effect or size of the area to be filled or the size of the shading you are applying. 

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.
