Callus File Keychain | Tough Skin Filer

This is a precision skin filer tuned to the sweet spot: OS780 grit removes rough edges without killing friction. The lightweight body and low-profile shape let you tidy fingertips and palm callus quickly, while the integrated keyring keeps it clipped to your kit so it’s there when you need it.

The abrasive layer is permanently bonded. No replacements, no rattling parts. Just smooth, controlled filing to help prevent flappers and splits. File smart, not deep - so that tomorrow is still your best performance day.
