This is the perfect weight for Pinewood Derby cars. Tungsten is a highly dense material which is almost as dense as pure gold. Tungsten is 1.7 times more dense than lead and 2.7 times as dense as zinc.
When you have a wafer thin car or are just trying to push your weight farther to the rear of the car, Tungsten is the ticket!
Each package of Derby Champ tungsten contains six 1/2 ounce cylinders, two 1/4 ounce cylinders, and four 1/8 ounce cylinders. They fit perfectly in to the pre-drilled weight holes found our blocks, wedges, and pre-cut cars.
* Tungsten is also non-toxic and environmentally friendly.
