I used it once, but it was too long, so I'm selling it. I purchased it under the product name "Hakata Kenjo Obi." It is not cotton or silk. I believe it's a blend of rayon, cupra, polyester, and cotton. It's softer than pure cotton and has a slight sheen. Length: Approximately 376cm Width: Approximately 9cm It doesn't slip and is not difficult to tie, but the item itself is well-made and has a luxurious feel. I used it once as a sword belt for Iaido practice, and due to storage, there are deformations and wrinkles as shown in the images. Please consider this, as it is not new (⋆ᴗ͈ˬᴗ͈)”
