Polycarbonate glasses are the answer to the problem of constant glass breakage and security. They look and feel almost like glass but have none on the disadvantages. Being almost unbreakable there is little chance of them being used as a weapon should trouble flare and their strength also makes them ideal for outdoor use, particularly in and around pool areas where broken glass could be an expensive nightmare. These glasses are stackable for ease of storage, ideal for where space is at a premium.
