This is an Otsu bag for a Natsume (tea caddy). It's used when putting koicha (thick tea) in a Natsume, or for a Chabako (tea box), etc. Approximately 23.0 x 11.5cm. It's a size with some room to spare when wrapping the medium-sized Natsume in the 5th photo (6.5cm diameter at the top, 3.5cm at the bottom, 6.5cm height. The Natsume is not included). Both the front and back fabrics are cotton. You can gently wash and iron it. Please consider it.
