The Dr. Scholl's™ Pedi Perfect Electronic Foot File is a best in class foot file with innovative roller heads that deliver superior hard skin removal for softer feet after every use. It comes with 2 Nano Tech™ precision roller heads: the Ultra roller head removes hard skin, while the Fine roller head smooths and polishes. A powerful dual-speed motor lets you choose gentle smoothing or more intense buffing, and Pressure Lock Technology supports safe, controlled exfoliation. It is waterproof for use on wet or dry skin, has a rubber easy-grip handle and a dust catcher to help keep things tidy, and it is rechargeable with up to 90 minutes of run time. To use, charge the device, remove the protective cover, make sure the roller head is securely inserted and clean, then turn it on, select a speed and gently glide the roller head over hard skin in circular motions without pressing too hard. Wipe or rinse feet and dry them afterwards. Pack Contents 1 foot file, 2 Nano Tech roller heads and a USB-C charging cable.
