Another advantage of the built-in capillary is better needle guidance, making the Capillary Cartridges incredibly precise. That means you don't need to overdraw the lines and can draw them in any direction. Crisp lines in no time without having to shift around seems almost too good to be true. However, the ink is equally dispersed on all individual tattoo needles within the Capillary Cartridge, even in enormous magnum combinations. As a result, you can fill any tattoo area faster because the ink flow is uniform, eliminating the need to go over it again. It also implies less stress on your customer's skin and more comfortable working conditions for you.
