Sailor Pro Gear Slim Green Demonstrator
With its vibrant semi-transparent finish, the Sailor Professional Gear Slim Green Demonstrator is a bright candy-colored fountain pen - just right to satisfy your writing sweet tooth.
With a color demonstrator, you get a semi-translucent view of the inner workings of your fountain pen. Please note that with all demonstrator pens, whether made by Sailor or another company, ink specks that would never be seen in an opaque pen will eventually show inside the cap and section.
The Sailor Pro Gear Slim Green Demonstrator is a mid-sized pen that will be a comfortable fit for most users. This writing instrument can be filled with bottled ink using the provided converter, and can also use Sailor brand cartridges.


The Sailor Pro Gear Slim Green Demonstrator with Rhodium trim fountain pen arrives in a Sailor presentation box and comes with two starter ink cartridges.
Unless requested otherwise, each pen or nib you purchase from us will be carefully examined, tested, and optimized for your personal writing characteristics before it ships.

I just got this pen as a gift to myself for passing a required seminar for my Ph.D. program. The green demonstrator is a beautiful pen with the nib perfectly tuned by John's team. It's currently one of three fountain pens I own (Pilot Custom 823 M with CI modification by John, Lamy 2000 EF, and this in MF). It's the smallest of the three and the line width is very close to the Lamy EF. I can see why people rave about Sailor's finer nibs, as these make clean lines while giving a good sense of what's happening to the paper (feedback). By no means is the latter an unpleasant sensation--this Sailor let's you know that you are writing.
In short, another great piece by nibs.com!
