I purchased them for a friend so have not used them. However, I was delighted with the look and feel of them and they make a fun gift. I added a chique insulated wine carrier to the gift box and they looked great together. Even though I knew how to assemble them into glasses, my friend is likely to have no idea, so instructions would have been a good inclusion. I had fun typing up my own with some wine clip art which I sent with the gift. I think these would work great thrown into a suitcase for vacation or weekend away.
