The device includes a coupling that releasably and resealably engages said first and second opening. The first container is preferably filled with a hot liquid and the second container is preferably filled with a cold liquid, which are separated by a wall defined by the coupling. The outer surface of each container define any of a number of various surface profiles for massage therapy, such as a plurality of protusions, dimples, ridges, or ribs.
