Good in terms of capacity, they are the largest glasses I have (they are almost like jars), but they are cheap glasses, meaning they seem to break easily. The glass is thin compared to other glasses. They do the job, but you are afraid of breaking them every time. For example, if you put a spoon inside the glass to mix something... you try not to hit the glass. And if you put one glass inside another... you are afraid it will break. I wouldn't buy them again.

For those of you looking for the absolutely huge glass, here you are!
After this, go to a flower shop.
Frappes, cocktails with endless ice cubes, beer, water, whatever you want.
I have been using them for over 20 years and I wouldn't change them for anything!
