Made in Germany, the Semerak body massager has 4 rubber hammers attached to steel springs that are made taut and released by the turning of 5 wooden wheels. When the wheels are run over an area of skin the subject experiences a pummeling from each of the 4 rubber hammers in turn. The force with which they strike can be adjusted by a screw at one end.[1]
