These glasses are Spiegelau of Germany's exquisite Platinum glass... Crystal clear glass, fine rim, weighted bottom.
All patterns are designed and painted by Jenni Hopfinger using a non-toxic, food safe acrylic enamel. Each is an original, each is signed and dated.
After air-drying for a few days, all glasses are heat-cured which dries and hardens the enamel.
Hand-washing with regular dish soap is recommended.
