These have been around for many years.
I used to have plastic beer mugs that I would freeze and drink soda pop or milk out off. The glasses have a layer of fluid that freeze in between the two layers of plastic. All you have to do is freeze the them. If you use ice cold beverages in them they work very well. Very cold drinks for sure.
If you making frozen booze drinks, you sould be just fine. If not, try cooling down,let say Vodka or other kinds of booze first, then mix them in the frozen glass/mug. It's also ok if you can't freeze the booze. [img]smile.gif[/img]
