The first thing you notice about the Gwen highball glass is its unique "lava lamp" shape. These glasses come in a set of 4 with an 18.5 oz capacity. JoyJolt''s Gwen alcohol glasses feel fantastic to hold. They are light enough so as not to weigh your summer mojito down, but not so light that you feel as though it would break when you set it down. Take a sip of satisfaction and see. When you are not filling your 18.5oz glass cups with a vibrant cocktail, you will also love using them as sturdy kitchen glasses and general drinkware. Nothing says "cheers" like the clink of crystal. But listen, because not all barware is durable enough for a celebration! Each Gwen glass is 2.5oz and crafted from Lead-Free Crystal, mineralized for durability, and the rim is 3mm thick! So go ahead and enjoy a fancy toast! And, because we used this particular polished crystal, you''ll enjoy the bubble-less, diamond shine. Long Island Ice Teas seem to quench even more, while Tequila Sunrise layers dance in their ''lava lamp''-esqe glass. - 18.5 oz Set of 4 Highball Glasses - Easy To Hold - Dishwasher Safe - Clear Lead Free Crystal - Comes Ready in a Beautiful Gift Box- Backed by a Limited 1 Year Manufactured Warranty
