Beautiful and useful, but very sensitive

The glasses are beautifully designed to keep hot things hot and cold Cool. Never has my latte macchiato remained so long hot - and I also have preheated the old cups. Due to the round shape of the bottom the beverage flows even more beautiful, what has a positive effect especially in coffee and cocoa.

The downside: The glasses are very sensitive and two glasses have already got a crack above the margin. This applies to the large glasses. I have the glasses normal rinsed in the dishwasher. Each glass is actually unique since blown.
