Magic Black™ is a unique, true-black spray-on chalk in a non polluting aerosol. It has been specially formulated to blacken and intensify black and to cover stains, discolorations and blemishes. Magic Black dries rapidly and stays on. Will not rub-off like ordinary chalk or even come off with water, but will wash out easily with Bio-Groom Shampoo. Works great on all long and short hair breeds, is non-sticky, non-irritating, and has a fresh, clean fragrance.
