Strahl Goblet 310ml Over 20 years ago the innovative designers of Strahl beverageware recognized the need for luxuriously elegant yet durable alternatives to glass beverageware. Since then, many inferior copies have entered (and left) the market, unable to match the superior manufacturing processes and stringent quality control procedures that continue to ensure Strahl beverageware is a market leader. Strahl beverageware is manufactured from the highest quality polycarbonate, enabling products to have pristine clarity and outstanding durability. Only polycarbonate enables us to achieve the look and feel of glass. Polycarbonate is so tough, it can also be used for bullet-proof glass and aircraft windows.
