Zippy devices were created for a kinesiotherapist who uses a golf ball to treat my feet. He had to trap the ball between the palm of his hand and my foot for therapy and he dropped it several times while working on foot circulation. The Zippy device is what we got when we put a 'handle' on the ball. Zippy puts golf ball massage for the entire body in the palm of your hand. Roll With Us! Made in Tempe, Arizona, USA.
