Solid cup made of tempered glass. Glass is the best way to store your brew; glass can be completely cleaned, 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 ensures both a good grip and that 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 for enjoying quality coffee "to go," whether you bring coffee from home or from coffee shops you pass on your way.
The cup is also excellent for drinking from without the lid.
Dishwasher safe.
The lid and silicone ring are in the color Moonlight/Purple-turquoise-ish.
