Key Klips help reduce the effects of moisture and temperature on the seating of sax pads. Since the Key Klips keep the pads "trained" to the tone holes, instruments using them stay in better adjustment, have fewer leaks, and have longer lasting pads.The newest version of Key Klips has a refreshing design. Still with a light touch, this model does not clamp the keys with a heavy pressure as with some other brands, rather it duplicates the touch of the musician closing the keys. This new versatile design will fit more models than our original key klips.
