These magnets are just as strong as the powerful
BY0X04 blocks, but include some plating defects that just don't meet our stringent standards. Some have sharp edges, and a few have tiny pits in the plating. Many have plating whose texture is uneven, resulting in an appearance that seems like it's a bit dirty, but can't be wiped off.
If these cosmetic details don't bother you, these surplus magnets are a great deal.
