KeepCup Brew Cork Glass Coffee Cup, 16 oz
KeepCup
Brew Cork Edition, Toughened Glass Cup with Natural Cork Band, 16 oz
Every use replaces a plastic-lined disposable cup, and the drink itself sits in glass. The plastic lid keeps it from the plastic-free tier; drink lid-off at the cafe and it effectively is.
A toughened glass cup with a natural cork band that replaces disposable coffee cups, which are plastic-lined and shed microplastics into hot drinks. The press-fit lid and plug are the plastic parts.
