Plarail 4 curved rail pieces As they were used by a child, there are some dirt, peeling, scratches, and discoloration in places. Please refer to the 3rd photo. I washed them with a neutral detergent, but some dirt could not be removed. I would be happy if someone who understands the above could purchase them. I don't know the exact product name, but I am not considering selling them separately at the moment.
