Authentic East German Superfest glass — sold individually. Superfest was developed in the 1970s by the Carl Zeiss Jena institute using a specialized ion-exchange tempering process that made it approximately 10 times tougher than standard glass. It was produced for a limited period and has been out of production for decades, making genuine pieces increasingly rare.
These are the real thing — not a reproduction, not a modern imitation. Clear, functional, and built to a standard that simply isn't made anymore.
