UV effect changes the tumblers base color in sunlight! For each case sold CMD Wholesale will donate $4 to Susan G. Komen to help research and fight breast cancer. The design is part of the cup and not vinyl or any sort of sticker. They are high quality and made to last! They are dishwasher safe however, we recommend hand washing to extend the life of the insulated tumbler. Each tumbler comes with a straw! This is a full wrap design however; seams maybe visible and image might not line up at the seam.
