Feels like pressing with your finger. Use pinpoint to release stiffness.
The steel core bar is made of low pliability and direct pressure is applied to the point of concern.
The arched shape allows you to reach hard-to-reach places. The bumps of the wobble will come true.

Please pay attention to the strength when using. If you use it on a soft surface of the skin, please use it over a thin cloth.
