207 gel pen features uni Super Ink to help prevent check and document fraud as well as a textured grip for superior writing comfort and control and convenient retractable tip.

Archival-quality, acid-free ink is also great for documenting and record-keeping. Ink is quick-drying and water-resistant. Pen design includes a stainless steel tip, distinct metallic accents and a high-quality finish. Refillable.
