This is a COFO balance board. It's a popular item known for its high quality and moderate resistance. I purchased it new, but I ended up never using it, so I'm putting it up for sale. It's brand new and unused, and comes with everything: non-slip mat, box, and instruction manual. It's sold for about 20,000 yen on major online shopping sites. The construction is surprisingly solid. I'm also listing it on other flea market sites, so there's a possibility of sudden listing cancellation. Thank you for your consideration.
