Get kids excited about hydration with color-changing tumblers! These tumblers have fun artwork featuring Bluey and her friends, and change color when filled with a cold drink—use ice water for the quickest change. The set comes with 3 drinking cups that have a 16.5-ounce capacity, which stack for storage and fit in most car cup holders. The tumblers also come with lids that press securely in place (listen for the snap), which help prevent splashes and spills when outside or on the go, and straws that keep drinks easy to access. You can mix and match the lids and cups to create different colour combinations. The material is BPA free and dishwasher safe. Fun and colorful, these tumblers are the perfect drinkware for kids' hydration.
