This comfort-grip pen has a specially formulated gel ink that embeds itself to the paper fibers to help prevent against check washing and document fraud.

Check washing is when criminals steal a check, wash off the ink, and adjust the "pay to" line or dollar amount.

Important documents to use this pen on include: checks, tax forms, contracts, prescriptions, leases, home mortgages, credit card applications, loan applications, birth certificates and passports.
