The material is pure silk. It has a lovely color and a dokko pattern. It's a simple design, but because it's a Kenjo pattern, it has an elegant and formal feel. The reverse side has a single line, changing the atmosphere, so you can enjoy both sides. It's a timeless design that isn't affected by trends. It's clean with no stains. Size: 15 x 352 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.
