Long size Elastic rubber Part that holds the kimono: Polycarbonate This is a regular-sized Korin belt with 30cm of flat elastic added. Comes in a box. Set of 2 regular sizes = 1750 yen When dressing in a kimono, having two Korin belts allows you to use one for the undergarment and one for the kimono, resulting in a very clean finish. I have other items for sale as well. Discounts are available for multiple purchases.
