Love your Stanley tumbler but hate the dings, scratches, and loud CLANK when you set it down? This Uvafly silicone boot is the answer! It's specially designed to fit the bottom of the popular Stanley Quencher H2.0 FlowState Tumblers (20oz & 30oz) and the Stanley Adventure Quencher (24oz). The key feature is the TALL and THICKENED design – it comes up higher on the cup than basic boots, offering way more protection against drops and bumps. The exterior has a cool honeycomb texture that gives you a great, non-slip grip so it won't slide around in your car cup holder. It's made from flexible, durable silicone. It also has a smart notch design that fits around the cup's handle perfectly. This boot does it all: anti-slip, anti-scratch, anti-noise (drastically reduces that metal-on-table sound), and provides cushioning against collisions. Installing it is a breeze: just make sure the bottom of your Stanley is clean and dry, then push the cup straight down into the boot until the air is pushed out and it's snug. We've got it in this eye-catching Neon Green, but there are other colors too. Keep your expensive cup looking brand new!
