The glass with superpowers. koziol’s SUPERGLAS is made from an unbreakable high-tech material developed and produced entirely at the company’s home in Erbach, Germany — where koziol has designed and manufactured since 1927. Its expressive faceted cut and highly brilliant finish give it the look of fine crystal, while the material itself shrugs off the knocks that would shatter ordinary glass.

Virtually unbreakable and highly scratch-resistant in everyday use, SUPERGLAS insulates roughly four times better than conventional glass, so cold drinks stay cold and hot drinks stay hot for longer. It is dishwasher-safe and stays clear even after more than 1,200 wash cycles without clouding — which is why it turns up everywhere from gardens, pools and campsites to luxury resorts, five-star hotels and cruise ships, anywhere broken glass is a risk.

Produced exclusively in Germany, the material is 100% recyclable, free of softeners, and backed by a 10-year guarantee.
