These bottles of purified water are available in 1 litre and 5 litre quantities to suit your studio's individual needs. Purified water can be used for many things around the tattoo studio. This includes creating ink washes by diluting the pigment with purified water to create a paler, more transparent version of the ink. It can also be used to help mix different inks together when creating a custom shade for tattooing. It can also revitalise any older inks that may have started to dry out and make them usable once more.
