The material is cotton. This is a beautiful and original piece with a lovely color and a striped design. It's reversible, so you can enjoy both sides. This half-width obi seems soft and easy to tie, and could be worn in a sophisticated or modern style. There are a few wrinkles, but it's clean with no stains.
