Cobalt Groove Handmade Glass Recycled Juice Drinkware (Set of 6)Bordered in brilliant cobalt blue, these delightful tumblers bring a festive touch to any table setting. The set of six comes from talented artisans for the Novica Handblown Collection. Vertical grooves add texture to the glasses. Because each piece is handmade, shape and size can vary slightly and tiny bubbles may appear within the glass. This exemplifies the hand blown technique, making every piece a unique example of blown glass craftsmanship.
