These marbelous massagers feel so incredibly good you may want to order two of them to avoid foot fights at your party! It's a simple, yet powerful foot massage that's easy and fun. Sounds crazy, but rolling feet over marbles really works - leaving feet tingly and revitalized after even 5 minutes of massage. Kit contains a rolling pool, marbles, a shooter marble and a simple foot Reflexology chart. Just inflate the rolling pool, pour in the marbles and gently roll feet over them. Try heating or chilling the marbles first for an unforgettable massage. If using them in a party, be sure to wash them with hot soapy water, or spray well with alcohol between uses.
