I purchased 8 of these champagnes through ebay.  When they arrived 7 were broken. Very disappointing.  Never had enough to share a bottle of the bubbly in these stems.  I have some water glasses that I have never seen.  Had them mailed to Buffalo (cheaper) to my cousin’s girlfriend and she has carried them to my mom’s house where they rest (along with some Heisey Orchid stems).  This etch was produced from the 1940s-60s.  I’m amazed that crystal can last, undamaged, for such a long time.  I love this stem.
