Sharpie S-Gel pens are generally considered effective for anti-fraud purposes, particularly against “check washing,” because their gel ink binds into paper fibers and is resistant to chemical solvents used to alter checks. While not explicitly marketed as “security pens,” their ink formula makes tampering difficult and often damages the paper if altered.
