It is a type of drinkware made from especially hard and thick glass and having a faceted form. It is a very widespread form of drinking glass in Russia and the former Soviet Union. This has certain advantages over the other drinkware, since due to its form and hardness it is more difficult to break. It is arguably more handy in usage on moving trains or rolling ships, where it is less prone to decline and fall, or slip from hands, and less likely to be broken when hitting the floor, compared to non-faceted types of drinking glasses.
