Hockey-puck shapes are traditionally round DISCS, which have been used in the sport of hockey since the 19th century. The term 'DISCS' is often used to refer to these shapes, as they are flat and circular in shape. The DISCS are usually made of rubber or plastic, and are designed to be durable and able to withstand the impact of a hockey stick. They are also designed to be lightweight, so that they can be easily moved around the ice. Hockey-puck shapes are an essential part of the game of hockey, and are used to pass the puck between players and score goals.
