This is a wooden balance board from Marumitsu, designed to create a body environment for optimal performance. It's challenging and fun, but I'm selling it because I haven't been using it much. Would be great for core training. I'm also including the rubber mat I purchased with it. (There are some fold marks from storage, but it doesn't affect use) Sizes: Main board - 25cm (length) x 60cm (width) x 2cm (thickness), 2,300g Roll bar - 30cm (length), approx. 6cm (diameter), approx. 400g Ball - approx. 7cm (diameter), approx. 200g Rubber mat - 50cm (length) x 92cm (width) - Brand: Marumitsu - Material: Wood - Features: Non-slip - Condition: Good There are no noticeable scratches, but there are some minor scratches and dirt. ■ Marumitsu Product Concept (excerpt from HP) For everyone who wants to perform better.
