Tungsten spheres, pellets, balls, shot - what ever term you like to call it, these tungsten weights are a great way to get your Pinewood Derby Car to its exact weight. These small BB like (BBB size actually) spheres will add a very small amount of weigh to your Derby car at a time. Installation is easy, just drill a hole and insert them. Or place into any cavity you have on the car and seal with glue or wood putty. Better yet, really dial in the weight by using our Tungsten Putty!
