The material is pure silk. This is a single-layered obi belt from Nishimura Orimono, featuring a white base with a red Kenjo pattern. It's elegant and definitely has presence. Nishimura Orimono is a long-established weaving house with over 150 years of history, and their products are exquisite, using high-quality silk threads with a beautiful luster. I believe it's unused, and it's clean with no stains. Size: 15 x 368 cm Hakata obi belts are easy to tie and don't easily come undone. Please understand that this item has been stored at home. I have other items for sale as well. Please take a look here: #emiHanhabaObi
