Nikki Secret Pumice Stone is the most natural and healthy way to care your foot. It can not only give you the best exfoliant but promote blood circulation, relieve fatigue and improve sleeping. The numerous and random small holes on the pumice stone can scrub your skin with no dead angles. Effectively soften and remove dry/hard skin, remove callus and make your body smoothly and shiny. Soak your feet for some time in warm water to soft skin, wet the pumice stone in soapy water at the same time to create a thick lather, gently scrub in circular motions all over your feet (especially on heels and soles). Rinse well when done.
