This is a set of 5 haori cords. I received these as a gift, so the materials are unknown. They were stored in a paulownia chest for a long time, so there is deterioration (slight peeling) on the pearl part of the item in photo 5, and also deterioration (discoloration) on the metal parts. Please understand that these are used items before purchasing. I inspect them carefully, but there is a possibility of overlooking something. Please understand.
