Thank you for viewing! (*^^*) This is an adult heko obi (soft sash). It's a reversible obi made of two types of fabric, including cotton. It is not a pre-tied obi. No interfacing is used. Size: Approximately 16 cm x 440 cm. Please understand that there may be some imperfections due to the fact that it is handmade by an amateur. It's a soft obi. I think it would be nice to use it with a single-layered kimono or yukata for the coming season. Thank you!
