I don't know the materials or the year it was made. I think it's been several decades. Please be aware that it is quite old. It's a decorative obi (sash) with patterns of autumn leaves, pine needles, chrysanthemums, and plum blossoms in red, green, purple, and white on a blue background. The otaiko (back part of the obi) is not pre-shaped by sewing. It's a single, flat piece, and I think you fold it and attach it to the han-obi (half-width obi) with a metal hook. I think an obi-makura (obi cushion) would be helpful. I don't know how to wear it. Please figure it out yourself. There are no instructions. Size: The width of the otaiko is 30.2 cm, and the length is about 72 cm. The width of the obi that wraps around the body is 15 cm. The length is 84 cm when folded in half. The tying cords were tied by the previous owner. The longer one is 40 cm, and the shorter one is 35 cm. If they are too short, please untie them yourself. From a quick look, there are stains on the obi itself, both on the otaiko and the han-obi. These are the areas circled in the images. The han-obi also has other light stains. The cotton cords for tying also have dark stains. There are fold lines. These wrinkles are from long-term storage by an amateur, as it was folded. The stains are a significant issue, so I've lowered the price. I only ask that those who can accept this please purchase. ⚠ I plan to use Yu-Packet Post, so I will fold it small enough to fit the size restrictions. Therefore, there is a possibility of wrinkles. Please open it as soon as possible after receiving it. I'm worried about the wrinkles increasing. ⚠ If your evaluation will be delayed, please be sure to contact me on the transaction page. ⚠ Currently, I cannot offer discounts on single items.
