My ideal - pumice Soviet times, since it is large enough and has a fine abrasive. For many years I could not find anything similar until bought by pumice Body Benefits. She: comfortable shape that is optimal for all cases of an abrasive, a good size for a comfortable lace-drying / storage. Moreover, the functionality of the pumice is difficult to overestimate: sharp edges sanded skin comfortable in confined spaces (eg, nails), flanks - fingers, and the main surface, thanks to the curved shape - the foot and heels (knees and elbows). Pumice removes the horny layer of the skin thoroughly, but delicately, not lost between the fingers, it fits comfortably in your hand. And it does not crumble, it is convenient to store and it dries quickly. *** If the review was useful, you know what to do.
