They have been stored in the original weather and mildew proof cardboard cases since 1969, but with time they are now stained brown in various places wherever the material was touching the box. It does not appear that the staining has caused any damage besides a discoloration. Our loss is your gain as we have priced this original issue trousers accordingly. These are the real deal, all new but stained. Closeout price, sold as-is. Sorry, no returns on these.
