Let me start by saying these are crystal and beautiful. I really like the way the flute is shaped, narrow on the bottom, widest about a inch below the rim. That shape adds to their beauty to me.
The way these glasses are made, I can easily see a strawberry in it with your champagne. Of course you could drink whatever you wanted out of these flutes, including soda if that's what you wanted.
I received this item at no cost in exchange for my honest opinion.
