The speckled patterns on these drinking glasses are created by rolling molten glass in colorful glass chips and millefiori slices before skillfully hand-blowing each piece into a glass form with an indented thumbprint for comfort while holding. Due to location alone, a set of six glasses from this workshop in Naples costs less than a set of two from Murano! No two are exactly alike; amount and placement of glass chips and millefiori will vary from glass to glass. Dishwasher safe. Handcrafted exclusively for Uno Alla Volta, from the heart and hands of the artisan. Dimensions - Approx. 5'' tall, hold 12 oz.
