Juliska glassware is mouth-blown by artisans in the hills of Prague. The unique composition of Juliska glass allows it to be blown especially thin, making the glass an unexpected pleasure to drink from and to handle. Being handmade, no 2 pieces of Juliska are identical. Each will have its own individual character - small bubbles and slight size variations. Dishwasher-safe on warm gentle cycle with mild detergent. Larger or highly decorated pieces - wash by hand.
