Lap Tatts are printed on a woven fabric based material with an adhesive backing. The adhesive allows you to easily adhere the Lap Tatts to the outside of your computer or other electronic device or any other surface for that matter. They remove easily and do not leave a sticky residue behind. Lap Tatts can be repositioned multiple times without losing their effectiveness. They are ideal for High School Seniors, Weddings, and Family/Child portraiture.
