MODEL- GMM                VENDOR- D'addario
   
FEATURES- Gripmaster Medium Tension
       Gripmaster is uniquely effective because each finger is isolated and
        flexed on an individual spring-loaded button.
       Gripmaster delivers total conditioning for each individual finger,
        the entire hand, wrist, and forearm.
       Beginners will leap months ahead in fingering strength and ability.
       Professionals can easily warm up before performances.
       Pocket-size and durable. Work out anytime, anywhere - even when your
        instrument is not available.
