Solid tempered glass cup. Glass is the best way to store your brew; glass can be easily cleaned thoroughly, so you avoid the "thermos taste" that occurs with most other materials, even after several years of use. This one comes with a practical silicone ring that provides both a good grip and ensures the cup doesn't get hot to hold. The practical lid can be pressed on and has a smartly designed closable drinking spout. However, the lid is not 100% leak-proof like a thermos. KeepCup is designed so you can enjoy quality coffee "to go," whether you bring coffee from home or from coffee shops you pass on your way.
The cup is also excellent to drink from without a lid.
Dishwasher safe.
The lid and silicone ring are black.
