SIZE AND MATERIAL: The drinking tumbler has a 12-ounce capacity and measures 3.2 inches in diameter and 6.77 inches tall. It's made of food-grade, 18/8 stainless steel with a silicone spout. The lid is dishwasher safe and can be disassembled for cleaning, while the tumbler should be washed by hand. Everything is BPA free and should not be microwaved. | VACUUM INSULATED: The water tumbler has vacuum insulation to keep drinks cold for up to 10 hours. The double-wall construction also prevents condensation from forming on the outside, eliminating messy water rings. | LEAK-PROOF DESIGN: The silicone straw spout 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. | AT HOME OR ON THE GO: The straw tumbler is suited for travel, since it won't leak and fits in car cup holders while keeping drinks easily accessible. It's also great for drinking beverages at home without worrying about stains or nearby electronics. | LIFESTYLE: Zak Designs drinkware makes hydration fun! This PAW Patrol tumbler is a great gift for any young fan or kids just graduating from sippy cups. The tumbler is fully reusable--no more disposable cups--and a fun addition to the daily routine.
