Gotta protect your prized Stanley tumbler! This Vmini silicone boot is designed specifically to snugly fit the bottom of your Stanley Quencher H2.0 40 oz and IceFlow 30 oz tumblers (note: not for the Quencher 30 oz). It's not just any boot – it has this gorgeous, glossy gradient finish that shimmers and changes color in the light, giving your cup a totally unique, dreamy look. But it's practical too! Made from thick (2mm), BPA-free premium silicone, it acts as a shock absorber and scratch guard for the bottom of your cup. It softens the landing when you set it down, provides a better grip, and helps prevent dings and dents from accidental drops. It has a little air hole design that makes it super easy to slip on and off. It's the perfect accessory to personalize your Stanley, make it stand out, and keep it looking new for longer. A great little gift for any Stanley fan who wants to add some sparkle and extra protection to their daily hydration buddy.
