This is an Otsu bag for holding tea caddies and tea containers. Approximately 23.3 x 11.7 cm. It's a size that comfortably fits the medium-sized Natsume (tea caddy) in the fourth 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 the same silk. You can iron it with care regarding the temperature. Please consider it.
