I had bought the glasses as tea glasses, because I just wanted to our decorative glass teapot also have beautiful glass jars, which are a bit extravagant. Due to the lack Henkel they are - and even more effective the insulation through the double glass. The insulation more so good that really is nothing to feel from the hot liquid from the outside. Now I have been drinking a few glasses of tea and coffee from it and I think it's always surprising to touch the glass and then to remember the mouth that there really what's hot in there. In addition, the glasses are nice and big, so you well a single glass can pour tea, if there is to be no time complete jug (normal tea cups are me as too small). The glass also fits just so under our Jura Coffee machine - has to be tilted only slightly under put and take out the - therefore there from the glasses now also coffee with nice crema beautiful to look through the glass. The insulation is a real wow factor!
