This is a replacement collar specifically designed for the "Kiraku" juban, which allows for easy attachment and detachment of the han-eri (half-collar) with a zipper. This item uses washable silk, allowing you to wash it at home. The zipper does not come into direct contact with the skin, and a soft nylon zipper is used, so there is no stress on the body.
