Tungsten Cubes are the easiest type of pinewood derby weight to pack in the tightest space. Unlike tungsten cylinders, tungsten cubes can easily sit side by side or on top of each other to form the tightest concentration of weight in a pinewood derby car.
- Each Tungsten Cube is 1/4" (.25"x.25"x.25") and weighs exactly 4.8g (.167oz)
- Cubes pack tightly which allows you to place weight in a small space. Precise weight placement in a pinewood derby car results in maximum speed.
