I've heard of molds to make ice glasses, but can not find anything on tumblers or wine glasses?
Is anyone known anywhere in the U.S. that sells these?
Those who are the "new" – they do not work, and if you alcohol in them, some of them only get a hole in them. I do not recommend them for actual use. They could be a fun gift, but they do not work. I have the glasses. I can only imagine something like a glass or a glass of wine would be even worse.
