About this item

• SIZE: The set contains two Zak tumblers that are 3.16 inches in diameter and 6.67 inches tall. They have a capacity of 15 ounces.  

• MATERIAL: The durable tumblers are made of plastic with silicone straws. Long-lasting and BPA free, they're dishwasher safe, can be disassembled for easy cleaning, and should not be microwaved.  

• LEAK-PROOF DESIGN: The silicone straw has a built-in valve that allows liquid to flow when drinking and prevents accidental spills when the tumbler is tipped over. The straw is also soft and comfortable for kids to drink from.
