We're happy to customize the tumbler for FREE! Please provide the exact name(s) you would like on the tumbler! You can put one or many names (see additional picture for example). If you have multiple tumblers needing ordered please add them individually to your cart! 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!
