Thank you for viewing! Large tumbler (cup) set of 6 purchased at Costco. It was quite large, so I only used it a few times and then stored it. The colorful colors are beautiful. It's also dishwasher safe, which is convenient. Height: 18cm Drinking opening: 9.4cm Capacity: 710ml Made of Tritan resin Please purchase if you understand that this is a used item.
