This is an obi I inherited from my mother. My mother, in turn, received it from her aunt. It's quite short, so tying it by hand is difficult. Using tools makes it manageable. There are many stains, and I had it cleaned once, but it didn't change much. Usable length for the front pattern: Approximately 73cm (the pattern extends to about 87cm to the triangle). Otaiko section: Approximately 75cm (excluding the hanging part). Taiko width: Approximately 31cm
