Worked great for childs Boy Scouts derby car race. This set of weights was the best deal I found for the weight considering that 3-3.5 oz tungsten weights are going for similar prices. The total weight ended up being 5.27, so when trying to stay under the 5oz requirement for Derby car racing this is a nice little extra weight.For Parents looking at these weights, our car won 1st place. It was a wedge shape with the weight in front of the rear tires (3/4 inch to 1 inch). Polish the axles with sandpaper so they are smooth, I put the nail in an electric drill to make the process faster. I use extremely fine-grit sandpaper on the tires too. A little powder graphite and the tires spin like butter. Good luck!

Worked well for getting pinewood derby car right to 5oz. Would buy it again because of the different sizes of weight in the package.

These tungsten weights are dimensionally accurate to the the listed dimensions to about .05mm of the dimensions listed. Tungsten is about 40% denser than lead, and is, of course, much safer than lead. The multiple sizes are convenient. Overall, I can recommend these.
