The Open Mini is a short bolt action ballpoint pen. At only 3.66 inches long, this pen is short to put in your shirt pocket. Its tough aluminum body has dynamic hollow rifling grooves that increase grip and just look amazing. The style is further enhanced by the blue body ring and ornate copper tail cap. The customized refill writes smoothly and won't become empty until it finishes 800 meters of lines. The L-type bolt action is intuitive to pop out and retract the pen tip. With the pocket clip, you can conveniently clip it to your notebook, pocket, or backpack strap.
