The AngelFeet file has a unique design and architecture, which make them one of a kind. The safety of an AngelFeet file is unparalleled because, unlike ordinary pedicure files, the AngelFeet collection contains no cutting blades or sharp edges . The files are etched out of a single piece of surgical-grade stainless steel. We create a surface of thousands of pyramids to safely remove dry, cracked and calloused skin. This technology makes the pedicure fast, safe and easy to perform, without cutting or grating the skin. Other files made of metal, paper or cloth substrates have many negative attributes that do not allow them to be sterilized and can cause damage to the skin.
