Review on ☕ Caffeine Molecule Coffee Glass - Embracing the Science of Caffeine by Keith Harris

The glass has a distinct seam where the two pieces meet. This cup barely holds a large variant of Kourig (300ml), so if a mocha drinker wants some of that great warm milk with sugar, they'll either have to use another cup or drink hot dark coffee. You have to give points for endurance. This mug is unlikely to break if dropped from 3 feet. Not that I tested it.
