This is a stylish obi with a bingata-style design. The photos, as usual, don't accurately capture the colors. The red appears flashy, but it's actually a subdued maroon. The back also looks like a vibrant blue, but it's a calm navy. It's more understated than the photos suggest. Since it's a solid color, you could potentially use the back, but there are some white threads visible in places. My mother, who bought it, is no longer with us, so I can't provide a detailed explanation. I believe the material is natural. It's a fashionable obi. I think this type of obi is rare. It has an elegant and gorgeous feel. It's very light. Please understand that this is a used item, so there may be minor imperfections. Please purchase only if you understand this. Shipping is 750 yen, plus fees.
