This pen is made to post, and there is a magnet at the cap’s end, making that easy and secure. It uses any Parker-style refill. It is shipped with a premium Uni Jetstream SXR-600-07 Black 0.7mm refill. I have only briefly been writing with the Roady Curacao Model, but I am already in love with it. It feels balanced and well-made in my hand. I love how smoothly it writes. Some people would say paying $60.00 for a ballpoint pen is ridiculous when you can get a whole pack of Bic pens for around $7.00. This is true; the difference is that twenty years from now, I could pick up the Roady Curacao Model 2 I received today and write with it. The Bic pen would be dust by then. If I can keep from losing it, this pen will be in my rotation for a long time.
