Kwadron Cartridge Flat Liner

Flat needles, commonly called flats, allow for precise shading as they are easy to angle correctly. Flats can also be used for outlining, as their shape allows for more ink delivery to the skin with each stroke. This means clearer, darker lines with a single motion. 

Larger flat configurations can be used for filling with color and shading, as they inject much more ink with each pass. Flat needles are good for intricate shading, such as in geometric patterns and works like mandalas.
