Got an Owala 40oz tumbler with a handle? Protect your investment with this simple silicone boot. It's designed specifically to fit snugly on the bottom of the Owala 40oz tumbler – but only the version with the handle (it won't fit the 40oz water bottle style, so double-check your model). This sleeve acts like a bumper, guarding against dents, scratches, scuffs, and general table wear. It's made from soft, flexible, food-grade silicone that's BPA-free and dishwasher safe for easy cleaning. Plus, it gives you a bit of anti-slip grip and muffles that 'clank' sound when you set your cup down. Comes in fun colors like 'Candy Store' (shown). Installation is a snap: just clean your tumbler's bottom, line up the sleeve, and press it on evenly to squeeze out the air. A cheap and clever way to keep your favorite drink cup looking new.
