Retail price: ¥12,000 Purchased at a major hospital specializing in knees. Only tried on. Since it seemed to be priced exceptionally low compared to other listings, there might be a misunderstanding that it's a cheap product, so I've corrected it to the original price. This is almost unused, made of sturdy material, and not sold to the general public due to its functionality. I'm listing this so that those who understand quality and read my profile can purchase it.
