This is a set of obi accessories for mourning attire: an obi pillow, obi age (sash scarf), and obi (sash). It's likely unused, and overall in good condition, but the obi pillow has a tear in one part (see photo 3). The obi has triangular fold marks. I don't know how to use these items or any other details about them. Obi size: approximately 145cm x 14cm.
