These are the four stemmed white wine glasses made from tritan, an advanced copolyester that will not crack or shatter, making them ideal for outdoor entertaining on the patio, by the pool, or in the boat. Their exactingly precise design replicates the nuanced bowl shapes of the finest crystalware, imparting an upscale panache that makes them perfectly suitable for taking in a wine‘s bouquet. The glasses’ BPA-free construction earns them FDA approval. They are microwave- and dishwasher-safe and won’t cloud or craze, even after 2,000 dishwasher cycles. 12-oz.
