Necessity is indeed the mother of invention. The govino shatterproof wine glass 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? Why does the govino wine glass look and perform like crystal??? The govino wine glass is made from a proprietary, food/pharmaceutical safe polymer, only 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.
