This is a silk (正絹) kasane-eri (layered collar) or date-eri (decorative collar). I purchased it for the retail price of 11,000 yen, but I have kept it stored in a dark place without using it. It is a new, unused item, but it has been stored at home, so please understand this before purchasing. The actual item is a slightly darker color than the photos. #KagaGosai #SilkDateEri #DecorativeCollar #DecorativeCollar #KasaneEri #DateEri
