Meet the world's first refillable, retractable, ball type pen; an amazing invention. If you enjoy the fluidity of liquid ink writing, look no further than the Monteverde Engage. Select the regular Engage click-top, or option-up with the Engage InkBall with a stylus on the top.The filling system draws ink from your choice of standard cartridges or your bottled ink and the included converter. The tip deploys with a click, so the inconvenience of having to cap your pen is eliminated. The inkball tip lasts for miles and miles and, if needed, is replaceable. The pen's body is made of carbon fiber for strength and weight reduction. It looks mighty cool too, trimmed in either stealth black or rose gold.
