Plarail Mini Bridge Piers Set of 12 I wiped each one down before listing, but there are still some stains that I couldn't remove. Also, since these are old, there is some discoloration due to aging. I'm not very familiar with Plarail, so I don't know the details... Please understand that I'm selling them as they are. Please also understand that these are used items that a child has played with. I don't want to just throw them away, so I would be happy if someone could use them. Thank you very much! Plarail Layout Bridge Bridge Piers Yellow Yellow Rails Tracks Plarail Bulk Sale
