Nylon pants purchased from Maison Special. I wore these often, so there are some stains. There is a noticeable stain on the back of the right leg, around the knee (see photo 11). There are also other small stains. Please check the photos before purchasing. Photos 16-17 show the locations of the stains, marked with circles. The circles indicate the approximate locations. I carefully checked the condition of the item before listing it, but I may have overlooked small or inconspicuous stains. Please understand this before purchasing.
