Set of 2 double-walled glass cups

Two double-walled glass cups. Clear borosilicate glass material. Dimensions are approximately 8 cm or 3.1" in height and 8 cm or 3.1" in diameter. Dishwasher safe. Used a few times but I don’t use them often enough to justify keeping them. Price is for the set of 2. 3 sets available (6 glasses total), other 2 sets are in their original boxes. Buy each set of 2 for $5 or take all 3 sets for $12 No crack/chips/scratches.
