To the basket of conscious pigmentation, I will add a machine that should be stable. Engine operation must be uniform. Machines that are better balanced are usually a bit heavy, but their vibration propagates in the skin, which in turn enhances the powdering effect and light work. I recommend working on optima cartridges, they are refined, the beak was fitted to the needle, therefore the work is even, and the needle does not fly in the beak. In addition, the needles are extremely precise and sharp. Perfect for any technique. It is worth emphasizing that they are made of medical plastic, which does not rub during operation and does not get on the skin.
