💛 Stickers are made with both water resistant vinyl sticker paper and water resistant UV laminate. 🩷 Tips and tricks: Not guaranteed dishwasher safe & should not be soaked in water. Always recommend hand washing if placed on water bottles to make them last a long, long time! Stickers love smooth surfaces in general and are not fans of powder coated water bottles. While UV-resistant, stickers should be kept out of direct sunlight for long periods of time. 🧡 This sticker measures 3 inches on longest side.
