Plunkett Percussion Wooden Bones, (approx. size: 1� x 1/4� x 7.5"), are custom shaped from Lignum Vitae, �Iron Wood�, one of the heaviest and strongest woods known to man. The density, consistent weight and balance of this wood, compared to any other wooden bones, particularly enhances the playing response and sound production. �Iron Wood doesn�t even float it�s so solid!�
