Brand new unopened box This set of tumblers will give hydration a fun twist: just fill one up and watch it change colors! Each tumbler holds 25 ounces, with a lid and straw to protect from splashes, spills and debris. They're a great choice to take outside or on the go, and fit in car cup holders. The tumblers are made from plastic, which is durable, lightweight, and easy to clean in the dishwasher, as well as completely BPA free.
