Simply inserting this during dressing will smooth out any wrinkles or distortions in the "ohashori" (the folded part at the waist) for a clean finish. It has a moderate softness and feels comfortable to wear. It can be used for everything from yukata (summer kimono) to formal kimono. Two pieces, front and back, are recommended for hanhaba obi (half-width obi) and furisode (long-sleeved kimono). Usage Tips: Inserting it after securing the collar with a chest string or datejime (under-kimono sash) may cause the collar to become misshapen, so it's best to insert it beforehand for a cleaner look.
