The super flexible design of our HW Pad-Saver® for Alto or Tenor sax goosenecks easily fits the curve of the neck where saliva and germs collect. Simply bend the flexi wire into a soft curve and insert it into the neck after playing. The ultra-wicking fiber will instantly pull corrosive moisture from every surface it touches, leaving your horn clean and ready to play next time. May be stored inside or outside the horn.
