Key item features

  • 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. 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 cute tumbler is a great gift for any young one or kids just graduating from sippy cups. The tumbler is fully reusable--no more disposable cups--and a fun addition to the daily routine.

Finally, a toddler cup that actually doesn't leak!

We have gone through so many toddler cups, but the Zak Kelso cup is a game-changer. It genuinely keeps drinks cold for hours thanks to the stainless steel insulation, and it has survived multiple drops without spilling a drop. The Mickey Mouse design is an absolute favorite for my toddler, too. Easy to clean and perfect for car rides!

Perfect Solution!

This cub is absolutely perfect for my 84 year-old mom with advanced dementia. With other cups, she would spill either while drinking or setting the cup back down. Sometimes she would turn it upside down because she couldn't tell the difference. You can shake this cup, turn it upside down, not so good don't worry about what everybody else don't oh no dude a drop on the floor, and there are no spills. Absolutely recommended. It is stainless steel and insulated. Excellent for hot or cold. I use it to give her coffee and also cold juices. Everything stays their temperature.

Nice cup

We needed some more cups for summer time. These are great. Metal to reduce the microplastics also the vacuum layer helps keep drinks cool. Cute space details. They can spill a little but not too bad
