Govino Stemless Go Anywhere Wine Glass Elegant, Shatterproof, Reusable & Recyclable Stemless wine goblets that are UNBREAKABLE!! Where Wine Meets Design Necessity is indeed the mother of invention. The govino shatterproof wineglass was originally created as a trade tool to help professional salespeople showcase their wines whenever and wherever proper stemware isn't accessible – which as we learned firsthand, is often! Once we began testing the market, we realized there was an even bigger need for govino in the consumer sector, particularly at settings where breakable glass is an issue. After all, how many times have we all had to endure drinking good wine from bad glasses?  The govino wineglass looks and performs like crystal.   The govino wineglass is made from a proprietary, food/pharmaceutical safe PETG.   It is superior in that it reflects the wine's color and aromatics much like crystal. It is recyclable (#1) but better yet it is reusable. Washing your govino wineglasses: 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 our product is 100% "dishwasher safe". If you still choose to wash govino in your dishwasher, you do so at your own risk. Save water and energy. When in doubt, hand wash! Reuse it, abuse it, but eventually recycle it! The govino wineglass is meant to be replaced after an extended period of use. Your wine deserves it!. Glass Specifications Width: 3.3 inches Height: 4.4 inches Mouth: 2.5 inches Volume: 6 ounces up to the mid point of the thumb notch - 16 ounces up to the brim
