The Denco Pumice Stone #3970 is a personal care tool designed for gentle exfoliation and removal of dead skin cells. This oval-shaped pumice stone comes from a brand established in 1968, offering an effective solution for skin smoothing and callus removal. This product is a personal hygiene item used for exfoliating and smoothing rough skin. As with any exfoliating tool, it's recommended to use gentle pressure and test on a small area first. The stone should be thoroughly cleaned and allowed to dry between uses to maintain hygiene.
