You will receive a bag of 60pcs mixed radial discs made in China. The color and grain do not match the 3M discs, so be sure to print them out from the product description. There is definitely a difference between them and 3M, they are very low quality. The spikes are nothing special, 3 of one size, 3 of another. I would buy radial 3M.
