450ml Transparent Borosilicate Glass Butt Coffee Mug
The Butt Drinking Cup is certainly a conversation starter, but beyond the cheeky aesthetic, it is a surprisingly solid piece of drinkware. I put this 450ml borosilicate glass mug to the test with both piping hot espresso and chilled water to see if its performance matches its bold look.
