This is an obi締め (obi cord) from Eriyoshi. I purchased it for about 13,000 yen. I tied it once and stored it for about a year. There is some slight fraying. (See photo 6) Other than that, it is in beautiful condition with no stains. This obi締め has a hollow core, making it easy to tie. It's beige with black edging, and a touch of silver thread adds a stylish accent.
