Rid feet of tough calluses without the harsh abrasiveness of a traditional Pumice stone! The Purple Pumi Bar has one flat side and one ridged side; each featuring Extra Coarse grit for ultimate callus removal (great for hands and elbows too!). Our custom formulation features synthetic frothed polyurethane and a sanitary solution to help prevent the unsanitary buildup of dead skin cells. This patented product produces a foot rasp with a uniform internal structure unlike any other. It’s a noticeable difference you can feel!
