I ordered four glasses recently, two of which I have given away (was super on), two I kept myself. They are regarded as whiskey glasses, however, I use it more as latte macchiato glasses. Although there are no thermal glasses but you can with no problems with hot contents hold. The glasses are also suitable SpĆ¼hlmaschinen.
I've been thinking, to order them again. If you want to but 4 glasses it is worth two 2-er to order sets, which is cheaper than a set of 4.
