Take your game to the next level with a Marucci Maple Wood Baseball Bat! These particular "BLEM" models indicate that there was a minor error in the manufacturing process of the finished bat. These blems can range anywhere from chipped paint to uneven grains. Blem models will still be structurally solid, but a cosmetic or minor variance from a standard model will exist. As a result, many players and parents find great value in going the route.
