The SmartCutter is THE revolutionary pedicure instrument for gentle and safe callus removal: The CREDO SmartCutter cuts the callus like a callus plane, but with the safety of a file or rasp. 30 small, three-layered cutting islands cut the callus very effectively with back-and-forth movements when a little pressure is applied, or file the callus gently with less pressure. The handle is made of plastic whose raw material is renewable sugar cane. Suitable for diabetics and haemophiliacs.
