Please read the profile before purchasing. This is a reversible kasaneri-eri (layered collar) without a core. It uses three types of fabric: cotton checkered fabric, glossy silk with a subdued red pattern, and plain black silk. Kasaneri-eri width: Approximately 5.5 cm x Length: Approximately 125 cm As I am a novice, please forgive any slight imperfections or errors. You can purchase directly without a comment. As this is handmade by a novice, please purchase from a store if you are looking for a perfect item. It will be folded small for shipping. No discounts for single items. I am a novice regarding kimono and related items. There may be errors in the types of materials used. Please review the images and purchase only if you are satisfied. There may be odors from aging, and I may overlook small stains or blemishes, so please refrain from purchasing if you are sensitive to these issues. ● Please purchase only if you understand that these are old items. ● Please refrain from purchasing if you are concerned about color fading, discoloration, stains, or damage, or if you place a high value on the color and texture of the fabric. ● The materials are mainly silk, the outer fabric of kimonos. ● Colors may not be accurately reproduced due to the characteristics of digital cameras and your monitor. Please refrain from purchasing if you are concerned about the image being different after receiving the item, as I would not want a negative review.
