Located in Chiba City, pickup is possible. Please comment if you are interested. I will lower the price if you can pick it up. The gray ones have a smaller inner diameter than the silver ones. The gray set is a full set, 12.5kg + core and fasteners. It can be up to 20kg with the silver plates. The silver ones are set evenly, about 10kg each. I am also selling an EZ bar that can accommodate all the plates in this photo.
