Thank you for viewing. This is a white summer ro-ori (crepe weave) han-eri (collar). The material is not specified, but I believe it is 100% polyester. This item was passed down from my family, who used to run a kimono shop. As I do not know the retail price, I am selling it slightly cheaper than similar items currently listed. I appreciate your understanding. There are currently 4 of the same item available. If you purchase 2 or more, or if you purchase this item along with other items, I will discount each item by 200 yen. Please let me know. Thank you.
