I wont be able to actually drink from these glasses until I move because it was just a first step essential for my first apartment. I did look at them and they are a tad bigger than a pop can, but Im sure you can still fill it to the top with some ice mixed in. Super cute and they feel like glass. Picture makes them look a little like cheap plastic like glass, but they seem reliable. Cute gift to get someone or when you dont want to drink out of the aluminum cans.
