Description The Sailor Pro Gear Slim fountain pen shown here in Christmas Pudding features a flat-top cap and barrel design in a slightly pearlescent dark brown resin barrel and translucent sparkly green cap, with a lighter brown grip section, accented by gold-plated trim. The 14k gold nib is available in a medium-fine or a medium nib. The cap posts well on the barrel when writing, and this helps to make the pen feel almost full-sized in the hand. The Sailor Pro Gear Slim fountain pen fills via the proprietary Sailor ink cartridges or proprietary converter for use with bottled ink - both of which are included with the pen. For the best long-term performance of your Sailor fountain pen, we highly recommend that you use the Sailor Fountain Pen Maintenance Kit for the most efficient way to clean your fountain pen! If you do not see a nib option that you would like for this pen, please Contact Us and we can make that happen for you!
