A Massage Knobbler saves wear and tear on your hands when working on tough spots, giving your hands more power when you need it. It's helpful in applying precise pressure to soft tissue trigger points. Cradled comfortably in the palm it leaves the fingertips in touch with the body to gauge pressure. Use either the tip or the base for applying pressure on yourself or others. It won't replace your healing hands, just help them do more for longer. The Knobbler massage tool is made from beechwood timber. Measurements: Height 6cm x 6.5cm (Top diameter) Price is for one.
