This 12-piece reusable tumbler set features color-changing technology that transforms when filled with cold liquids. The set includes 3 orange, 3 lime, 3 sky blue, and 3 pink tumblers that change to red, emerald, navy, and purple respectively. Each tumbler holds 24oz and comes with a splash-resistant pop-on lid and reusable straw.

The tumblers are made from BPA-free plastic and measure 4 inches wide by 7.25 inches tall. They are stackable for easy storage and fit most standard cup holders, making them ideal for on-the-go use. The durable design is perfect for parties, picnics, and everyday use, and the cups are easy to personalize and decorate at home.
