For when you want to dilute your pigment, without diluting the quality. ;-)
Some artists prefer a slightly more fluid consistency for their appointments, (for example for ombre eyebrows). Of course when diluting your KremaKroma you don't want to just use any old substance to dilute it.
This diluent is made from EXACTLY THE SAME base, just without the color... it is of a 'gel' consistency, whereas standard KremaKroma pigments have a rich, creamy texture.
Of course, the shelf life is 5 years... just make sure you shake it a little before use!
