Overall, it’s a good reusable cup! They look great and function as quality semi-disposable insulated mugs. Have used these daily for over two years with zero issues. These unique eco friendly coffe cups are perfect for on the go folks.

Keeps coffee at the perfect drinking temp during a 45 minute commute. Feels comfortable in your hand.

I like my coffee scolding hot and these stand up to the test. They fit in cup holders, they are light, and can be put in a dishwasher. The cork will be damp for a couple of hours, so buy a couple.

The lids have a rubber gasket in the liner to stop leaks. The threaded lid is secure and i have never experienced any leaking problems in the year since i bought one.

It's at least as much as if you poured from the sipping hole. Can't recommend these. May as well use a regular coffee mug.
