1/4 ounce Tungsten Cylinders -1oz kit

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 tungsten contains four cylinders (3/8" in diameter, 1/4" in length, and weigh 1/4 ounce each). 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.
