Coarse Callus Grater Rasp: For severely callused, dry feet. On clean, dry feet, carefully pass the blade side across callused areas. Increase pressure as needed and to what you are comfortable with. Use with caution. 

Use the coarse callus file only when needed, and with caution.

Fine Foot File: Removes minor calluses and dry skin from feet. Can be used wet or dry. With gentle pressure, scrub away at your dry areas to reveal softer looking feet.

Use the fine foot file every 5-7 days, or as needed.

Care: Wash tools with soap and water after each use to prolong their longevity.
