This is a drawstring bag for Japanese traditional clothing. The color is navy blue. The bottom of the drawstring bag is square, with each side being 15cm (see photo 2). Please check the pattern in photos 3 and 4. The strings are yellow, so it might look good paired with a yellow obi. I bought this because I wanted a drawstring bag to match a navy blue yukata, but I no longer wear navy blue yukata, so I'm offering it for sale. How about using it for outings when the weather gets warmer?
