Flexdex performance skateboard material is an engineered unlaminated fiberglass composite utilizing 6 different resins and fiberglass. These boards will never delam, break, or die. Ever. Guaranteed. Flexdex composite decks in black, white, gray or green are made in a process that inter-twines and binds all the resins and fibers in such a way that the boards will never delaminate or lose their spring. Frankly, it takes 30,000 pounds per square inch of pressure to reach a point where you can damage the deck. So you can be assured of years of flexing and carving. This guarantee is forever. They are not warranteed for scrapes or bumps.
