Retractable smooth-flowing gel pen has specially formulated ink that aids in preventing check and document fraud and helps preserve document integrity and security. The intense colored pigment ink soaks into the fabric of the paper and cannot be removed with everyday household chemicals such as acetone, benzene, or bleach. Gel ink is acid-free and archival-safe. Tinted barrel reveals the remaining ink supply. Refillable pen includes a latex-free rubber grip for added writing comfort and a safety clip that does not allow the pen to be placed in a pocket with the point exposed.
