Balance ball, diameter 35-40cm Includes air pump. No box. I inflated it, but the size wasn't what I expected, so I'm selling it. I only inflated it, and haven't used it. I've wiped it down with an alcohol wipe to disinfect it. The box is not included. [Product Name/Features] Balance ball *No box Size: Ball/Diameter 40cm Air pump/23 x 3.5
