MOMs tattoo ink in Doo Doo Brown. This is, as the name suggests, a poo brown color, so if you are tattooing a piece of crap, this is the perfect shade for it. MOMs stands for Millennium Color, this company has been a mainstay of the industry for many years. You can ask any old school artist if they know MOMs and we are sure at some point of their career they have. These pigments are pure, uncut, homogenized pigment dispersion. This stuff consists of a time tested formula that has remained consistent for many decades. These colors are made in the USA by Technical Tattoo Supply.
