Thank you for looking. This is a set of three types of cotton fabric. It is reversible. No interfacing is applied. It is one long obi (sash). There is a seam. Size: Approximately 16 cm x 410 cm. Since it is handmade by an amateur, there may be some distortions, but we appreciate your understanding. ★ It is a soft obi. It would be nice to use it for a single layer kimono or紬 (tsumugi) in the coming season. Thank you.
