The Felt Store’s Cup Sleeves are both reusable and cozy! Instead of using a disposable paper sleeve, start thinking sustainable with our industrial felt sleeves made out of wool and recycled fibres. Felt is a natural insulator and is great for keeping your hot drinks warm and your hands protected. Our felt sleeves are adjustable to two sizes, making them fit a variety of cup dimensions while easily being stored in your purse or glove compartment. To clean, simply hand wash and hang to dry.
