Derby Monkey Tungsten Cylinders are 9.8mm in diameter x 10.5mm in length and weigh 0.5 oz each. These are the standard size cylinders. These Tungsten cylinders are made specifically for Pinewood Derby cars.
Tungsten is the world's 4th heaviest metal. It weighs up to 1.8x as much as lead and over 3x the weight of the Zinc/Pewter weights. This is the perfect weight for Pinewood Derby Cars.
Tungsten is a safe non-toxic metal and it takes up less space in your car. Less space, means more weight concentration in the CG area, faster building time and more speed on the track.
