These waterproof vinyl stickersare super adorable! They stick on my wterbottle but also on my phone and phone case! Since there are so many things tht we have that are alike in this house, these make it easy to see who's is who's! We just picked out the sticker (or stickers) we wanted and put them on! Easy to apply! They are waterproof and sun fade resistant. Also if you are not satisfied with them you can just return the whole pack and get your money back! Doesn't get much better than that!
