govino really means go anywhere you like. This revolutionary vessel designed for the ultimate enjoyment of fine wine actually works well for any cold beverage. The unique ergonomic thumb-notch makes wine swirling most simple and best of all you can reuse them or even recycle them. Each box comes with a set of four crystal-clear shatterproof "glasses" perfect for indoors or outâ€"at a picnic, an outdoor party, or at poolside. The govino wine "glass" is actually not glass at all. It is made from a proprietary, food-safe / pharmaceutical-grade polymer "aka" PETG, which reflects a wine's color and projects its aromatics much like crystal. Best of all... once your vino is gone your govino can be reused or recycled. Reuse it, abuse it, but eventually recycle it! To ensure the optimum wine tasting experience, replace your govino wine glasses after an extended period of use. Important Note: Hand wash only! govino was designed for commercial use and can withstand most industrial glass sanitation systems (1-2 minutes at 160 degrees). Since domestic dishwashers are so widely varied, we cannot claim this product is 100% "dishwasher safe."
