The Sarasa features a fine 0.4 mm gel pen tip that is sturdy enough to endure hard writing pressure, drops, and other pen abuses. It's also retractable, has smooth writing, is affordable, and is even made of recycled plastic. The ink is water based, pigment gel ink and is acid-free as well as archival safe. All of these characteristics make it a favorite for travelers and office workers who want a high quality pen you can take anywhere, and yet lose without too much monetary sorrow. Nine colors available including: black, blue, blue black, green black, magenta pink, mustard yellow, olive green, red and red black.
JetPens has two versions of the Sarasa gel ink pen. One has a standard clip and one has a push clip that can be used to attach the pen onto thicker objects such as binders.
