Contents: 6x heat-insulating, double-walled coffee glasses/tea glasses (height 10 cm, capacity 250 ml). Item number: 0901392000 Material: double-walled borosilicate glass, extremely cold and heat-resistant, scratch-resistant and dishwasher-safe.

The distance between the wall makes it look like the drink is floating The double-walled coffee glasses are a nice gift for men and women who like to drink coffee - whether as a birthday gift, for Christmas as a Christmas gift or as a secret Santa gift
