Yes, the wine glasses are virtually invisible thanks to the latest in glassware technology from Ravenscroft. I sampled their invisible cab/Bordeaux glass this past weekend, and I can testify to the invisible-weight nature of this glass. The lead-free crystal glass allows the aficionado to appreciate the wine to the fullest extent possible without the extra weight of lead-burdened glass. Wine lovers who want to know more about this new development in glass technology should visit Ravenscroft.
