The Franklin NHL Pro Commander Puck is the perfect puck for the roller hockey player, the ice hockey player looking to practice outside of the rink, and the street hockey player who needs a durable and reliable puck to use. Made with steel ball bearings, the Commander puck can move at high speeds to mimic gameplay on a frozen surface. Knurled edges provide additional grip, while hardened plastic construction ensures the puck will last time and time again.
