Pumice stone (natural volcanic rock)

Remove calluses naturally with the natural pumice stone from w.o.d.welder

Well-groomed hands with little calluses are less likely to tear during kipping-pull-ups, toes-to-bar, training with weights and other sports that put strain on the hands.
The calluses on your hands should be the same height as the rest of your palms to reduce the risk of injury.
To do this, use the pumice stone to sand off your calluses and thick areas of skin on your hands.
The easiest way to do this is immediately after a shower or bath, when the skin has been softened by the water.
