Sweet Starling Co. Tumbler Boot

The Checkered Hearts Tumbler Boot is designed to fit most standard insulated tumblers. Because silicone is flexible, it stretches to accommodate a wide range of base diameters, making it compatible with major brands like Stanley, Simple Modern, and Yeti.

It depends on your vehicle's cupholder size. While the silicone adds a small amount of width to the base, most standard cupholders can still accommodate the boot. If your cupholder is exceptionally tight, you may need to remove the boot for a perfect fit.

Cleaning is simple. You can either hand wash it with warm, soapy water or place it on the top rack of your dishwasher. It is made from durable, food-grade silicone that withstands high heat without warping.

No, the high-quality, food-grade silicone is non-porous and designed to stay clean. It will not leave sticky residue or marks on your drinkware, even after extended use.
