The material is pure silk. It has a Dokko pattern on a vermilion background. It has a simple design, but because it's a Kenjo pattern, it has an elegant and formal atmosphere. The back is plain. It's a timeless design that isn't affected by trends. There are a few wrinkles, but it's clean with no stains. Size: 15 x 346 cm Hakata obi are easy to tie and don't easily come undone because of the silk's texture. Please understand that this item is stored at home.
