Flash Tattoos are jewelry inspired temporary tattoos. They are quick and easy to apply and last about 4-6 days. Flash Tattoos come in sets of 4 sheets. Non-toxic and safe for anyone to wear. All Flash Tattoos pass safety standards for the cosmetic and toy product industries and meet all U.S. and international regulatory requirements. 5% of the proceeds of this collaboration will benefit Waves For Water, an organization dedicated to providing clean drinking water in impoverished areas.
