They are simply the best made tumbler you can buy from every stand point.
My coffee stays hot and easy to carry around!
This cup has kept my drinks cold overnight. I've accidentally knocked it over and it didn't get scratched. The seal is actually spill proof. Fit's perfect in my car and is very light.
Dishwasher proof, no sweating, ice feature keeps things really cold, chipped ice will become one- really cold drink & can last over night. Nice holding coffee hot.
They keep things hot or cold as needed. They come out of the dishwasher looking brand new. they are really well made and useful.
