This is a set of four pairs of pants. The size is 90 for the Moujonjon dinosaur pattern, and 80 for the others. I think the Moujonjon pants are about the same size as the 80 size ones. I inspected them and found no stains, but there may be some overlooked. Please understand that these are used items before purchasing.
