Original Jacknobber II

The knobs at each of its four points can be used in many ways to apply deep pressure to muscular trigger points. The smaller knobs provide deeper, more intense pressure.

The larger knobs provide broader, gentler pressure. Use one knob at a time to press deeply into imbedded trigger points; use two knobs at a time on either side of the spine.

Easy to clean with warm soapy water. Dishwasher safe. No not microwave.
