I'm selling a balance board I bought about a year ago. I haven't used it much, so I'm letting it go. Recommended for those new to balance boards. The protrusions on the bottom aren't overly sharp, so they're gentle on your feet. Overly sharp ones can hurt your feet. Both the top and bottom surfaces have good grip. It's a decent size, and shipping costs will be high, so I'm afraid I can't lower the price. Thank you for your understanding.
