Abstract: A folding case is provided for transferring hair-coloring chemicals to a selected bundle of hair. The folding case has a pair of opposing shallow compartments that are adapted for containing a pre-charge of color-base hair-coloring chemicals in one compartment and a pre-charge of activator therefor in the other compartment. Peel-away films are provided to cover and seal each compartment in order to seal in the respective pre-charges therein not only to keep the respective pre-charges separate and apart from each other and avoid pre-mature interaction therebetween but also to keep each pre-charge fresh and preserved during transit through a supply chain from a place of manufacture or production to a remote later-time of and place for end-utilization.
