Great waterproof sticker for your water bottle, laptop, phone case, and much more! †TIPS* - The sticker is waterproof, but we recommend hand washing rather than using the dishwasher because of the extreme heat that is used in most dishwashing cycles. - We recommend cleaning the surface where the sticker will be stuck so that the sticker will stick to the surface rather than any dirt and dust that may be on it. - Do not apply to a wet surface.
