Tired of your favorite tumbler sliding around or getting scratched up? These uxcell Silicone Boot Sleeves are here to help! You get two sleeves, each measuring about 6 cm in diameter and 5 cm high (that’s roughly 2.4 x 2 inches). They’re made from durable, flexible silicone that grips surfaces to prevent slipping and protect your bottle from dings and scratches. Plus, they help dampen noise when you set your cup down — no more loud clunks! They fit most 12–24 oz tumblers, but make sure to measure your bottle’s base first. Installation is a breeze: just wipe your tumbler clean, then slide the boot on, squeezing out any trapped air. They’re easy to clean and reusable. Whether you’re using them at home, in the car, or at the office, these little sleeves add both protection and stability. A simple, affordable upgrade for your drinkware!
