The Brushworks Curved Foot File keeps feet super soft. This double-sided file is ergonomically shaped and fits the contour of the heel. It is perfect for exfoliating thickened skin and calluses, immediately softening the feet. The abrasive surface is curved to gently hug the heel and delicately remove calluses on the sole of the foot. The product is PETA certified: cruelty-free and vegan.
