The material is pure silk. The gentle, elegant color and the patterned background are very stylish, and it has a sophisticated, high-quality, and beautiful design. It's reversible, so you can enjoy both sides. I believe it's unused, and it's clean with no stains. Size: 15 x 392 cm Hakata obi are easy to tie and don't easily come undone because of the silk's texture. Please understand that this has been stored at home. I have other items for sale as well.
