This is a used daytime/nighttime obi (sash). Flower capital Signature/Seal Some kind of mark I don't know the value. I was told it was silk when I bought it. I've worn it many times. It's old, so there is some age-related deterioration. Please understand that it is used. There are dull spots and stains. I didn't mind and wore it. Purchased from an antique obi shop. Retro I bought it because I liked the solid black lining. The color is a unique, muted greenish-brown, like the color of a dusky Japanese bush warbler. A green like the color of moss. It's a rare color. It looks like it has a calm, mature elegance. It seems to lack an obi core, making it very soft and easy to tie. The back looks like a woman in a Takehisa Yumeji painting, with a soft, relaxed finish. The Ginza knot had a nice drape. The material is believed to be silk. It is listed as unknown. If you only buy silk, please refrain from purchasing. Please make your judgment based on the photos. Length: 28cm x 367cm Purchased from an antique and recycled kimono shop that has been in business for many years. Measurements are approximate, so please understand that there may be some errors. I was told it was from an old era when I bought it. I'm not sure when it's from. As it is an antique item, there may be some stains, dirt, scratches, and discoloration in addition to those in the last photo. We appreciate your understanding and purchase. We ask that those who are familiar with antiques purchase this item. Shipping will be done by folding it small and with simple packaging. I apologize if it gets a little wrinkled. Thank you for your understanding. It can also be used as a table runner. If you are concerned about the smell of the chest of drawers or wrinkles, please refrain from purchasing. Thank you for reading to the end and for viewing.
