Moose blank decks are made of 100% Rock-Hard Canadian Maple from one of the premier manufacturers in the world. They have a representative at the factory that ensures only the best decks that will become a Moose Skateboard Deck. The ones that didn't reach the desired quality, are sold to everyone else. "Blank Deck" refers to absence of a graphic on the bottom, and says nothing about the quality of the wood itself. Originally "blank decks" were blems and therefore weren't printed. They were then sold at discounted pricing. Today, "blank decks" are out selling graphic decks in many areas. Beware that all "blank decks" are not created equal. Many people sell blems(seconds), and sell them at a super low prices, because that is that they worth, very little. Others buy whatever decks they can get cheap!!! For example Chinese Maple wedged between plies of Canadian Maple to hide it's appearance and lower the cost. Be careful in purchasing "blank decks" lower quality will result in ply fatigue & delamination, and your need to replace this poor quality product.If it doesn't have the Moose seal of approval, then your not skating the best.
