The PRITECH Electric Foot Callus Remover helps you maintain smooth feet by efficiently removing hardened skin. This lightweight device weighs just 0.28 kg and features an ergonomic design that fits comfortably in your hand during use. It is powered by a rechargeable lithium-ion battery that provides up to 45 minutes of runtime after a 2-3 hour charge. You can choose between two speed settings to match your needs, with a standard mode running at 1900 RPM and an intense mode reaching 2200 RPM. To handle different levels of callus buildup, the tool comes with three interchangeable roller heads in fine, regular, and coarse textures. Because it has an IPX6 waterproof rating, you can safely use it on both dry skin and wet skin after a bath or shower.
