Plywood Laboratory is a factory brand of plywood products by the long-established plywood manufacturer Takizawa Plywood in Hokkaido using Paper-Wood, which it developed uniquely in 2009, as the main material. Paper-Wood is a plywood that has a colorful and beautiful cross section. It was born of an innovative method involving the lamination of colored recycled paper and wood grown in Hokkaido and possesses an appealing expression that other materials do not.
