25oz Stumbler Tumblers by Beach Cubbies

These patented tumblers have a unique feature - there's a secret compartment on the bottom of the tumbler that unscrews and comes off!  Perfect to hold snacks, small items or more of your favorite beverage ;-)  Made from strong ABS plastic exterior and virgin food grade plastic interiors, these are sure to be a hit everywhere. Fits in most cupholders. Sweat-free design.
