The Velvet Smooth Electronic File is a product that helps you to get soft and beautiful feet immediately. It has a head to remove calluses, and an exfoliating head to remove dry, flaky skin. It is perfect for use on both dry and wet skin. It has an ergonomic design that makes it easy to grip, 2 speeds to adjust to the needs of the skin, and a safety stop that locks the head if too much pressure is applied. This pack also includes the Cracked Heel refills, which are concave heads designed to better adapt to the shape of the heel, helping to remove cracks in the skin for softer, smoother skin.
