This is a Lumilock hanhaba obi (half-width obi). It's made of a smooth, snakeskin-like material that's easy to tie. I believe it's made of polyester. Length: 400 cm Width: 16 cm It's in good condition, but please refrain from purchasing if you are concerned. Returns are not accepted, so please understand. I will not be offering discounts! Thank you for looking.
