I created a two-piece obi (a type of pre-tied obi) from a beautiful, like-new fukuro obi (formal obi). I believe there are no noticeable damages or stains. The length of the obi for the waist wrap is 185 cm. The otaiko (the back part of the obi) is secured with Velcro, so you can adjust the size of the otaiko to some extent. Since the otaiko is not sewn on, you can store it flat, which prevents crease lines and allows it to be stored in a tatoushi (a special paper wrapping for kimono), which is a great advantage. ○ Information on Obi Pillow Base Two-piece obis without fasteners tend to slip down, so using a separately sold obi pillow base will prevent the otaiko from slipping down, providing peace of mind.
