These donut-themed water bottle stickers are absolutely adorable for a birthday party! You get 20 waterproof wrappers that measure 1.75x8.5 inches each - perfect for fitting around standard water bottles. The design features cute donuts with frosting and sprinkles plus the funny pun 'Donut Grow Up' which is just perfect for a kid's birthday. What's really great is they're printed on waterproof label paper, so you can chill the bottles in the fridge or put them in a cooler without worrying about the labels getting ruined or the ink running. They're designed by a mom right here in the USA, and you can tell the quality is better than those cheap thin labels you sometimes see. Application is super easy too - just peel off the backing and wrap them around your water bottles after removing the original labels. They instantly transform plain water bottles into coordinated party decor that matches your theme. Whether you're doing a full donut-themed party or just want to add some cute touches to the drinks table, these stickers make everything look more put together and festive. Definitely one of those small details that makes a big difference in party planning!
