Four Chinese made, cast iron, black, powder coated 7.5kg weights, one inch bar diameter.
I bought these to replace a horrid concrete/vinyl York dumbbell set, plus a gain a useful bar weight increase from 17kg to 30kg.
The weights needed a wipe over to shift the residual black, a month on and no sign of any rust.
Poor postman, a 30kg box, looks deceptively light! He was ever so happy that I was working from home that day :)
Loses a star as the price has increased significantly since I purchased this item.
