Hello, Norway.

In professional play they use between one and three dozen in a game. When they are chipped like this one they replace them. This puck is perfectly good for our games and would normally be used again. I like to give the officials a new, frozen puck at the beginning of each game. Freezing the puck makes it slide faster and bounce less. I take three new, frozen pucks to each game. When the puck comes back looking like this I throw it in the coaches practice puck bucket to use during practices. They are made of hard, vulcanized rubber. These ones cost around CA$40 (25 Euros or 290 Krone.) for a dozen. As to othere uses, you put them in a sock and use them as a mele weapon.
