These wine glasses are nice and tall, great material, and very clear. It felt a bit like very high quality plastic because they don’t make the same sound glass makes when you clink them together and they are very lightweight. However, after educating myself, when you tap Crystal, the sound is more of a reverberated ringing, which these wine glasses do make. Additionally, the packaging was superior. These wine glasses were pa led very, very well. No broken glass, no scratches- they were delivered in 1 piece and are perfect. Absolutely beautiful and great quality wine glasses.
