Hey Stanley cup owners! If you're tired of your expensive tumbler getting all scratched up or making that annoying clanking noise every time you set it down, this silicone boot is an absolute game-changer. Specifically designed for the Stanley Quencher H2.0 FlowState 64 oz tumbler with handle, it fits like a glove with inner dimensions of 4.4 inches in diameter and 2 inches tall. The 2mm thick silicone provides serious protection against dings, scratches, and drops while dramatically reducing that loud metal-on-surface noise. Made from flexible, BPA-free silicone that won't deform over time, it's safe for kids and easy to clean - just toss it in the dishwasher! Installation is a breeze - wash it first, place it on a flat surface, pop your Stanley in, and squeeze out the air for a perfect snug fit. The rose quartz color looks gorgeous and adds a nice pop of color to your cup. Seriously, for such a simple accessory, it makes using your Stanley so much more enjoyable and protects your investment. Perfect as a gift for fellow Stanley enthusiasts or just treating yourself to keep your favorite tumbler looking brand new!
