The Aura Foot Care System is a 3-in-1 electric foot file that exfoliates rough skin and softens calluses with ease. It features 3 interchangeable grinding heads for a customized skin treatment - the coarse head deeply removes stubborn dead skin, the medium head lifts away rough patches, while the fine head is suitable for daily maintenance. Switching between the polishing heads is simple, allowing you to target specific problem areas or use the appropriate level of exfoliation for your skin's needs.
