Designed upon commission by Roman Vrtiska (Czech Republic) and made exclusively for Teroforma at Kvetna Glassworks in Czech Republic. The spare lines of these mouth-blown, non-lead crystal tumblers create a look as simple as it is refined and their easy stacking means they are a snap to store efficiently. Specifically designed for vodka and gin, the tumblers work equally well for any spirit where quality is more important than quantity. Available in clear and three colors. Dishwasher safe.
