Someone handed you an Ecnoy boot. If you’re wondering what that is: a decorative silicone sleeve that slips onto the base of your tumbler. There are practical reasons people use tumbler boots. Ours exist for the aesthetic and the personality.
This one wasn’t quite shop-perfect, so instead of sitting in a bin it found its way to you. We hope it earns a place on a cup you love.
It fits most 20–40 oz tumblers — check the fit guide for yours. Slip it on, and the straw topper goes right where you’d expect.
