This lime green resin pocket-sized fountain pen is the Esterbrook JR, short for "J Reborn". A modern take on a vintage classic, it is complemented by gold-plated trim and purple accents on the top finial. It fills via standard international cartridge/converter (included) and has a gold-plated JoWo #5 stainless steel nib.
The Key Lime is part of the limited edition seasonal Paradise Collection of Esterbrook JR pens.
For the latest additions to the Paradise series, we headed southward to the unparalleled beauty of Key West. With a vibrant cultural history, we could think of no place more colorful to highlight the newest JR's, Key Lime and Purple PassionBecause even the most refined fountain pen lover needs a tropical vacation, we are pleased to introduce our first limited edition, seasonal offering of “JR” pens, the Paradise Collection.
But what's really exciting about this pen lay in the small details. We think of Key Lime and Purple Passion as sisters, a set that's complementary to one another. On top of the Key Lime pen, you will find a gold finial encircled in purple. On the Purple Passion, you'll find the same but in a lime green. This little bit of contrast highlights the overall appeal and is again a homage to Key West, where nothing is as it seems and adventures are just waiting to be uncovered.
The “J” was the original Esterbrook’s sleek and suave, classic 1940’s and 50’s pocket pen that appealed to the practicality of the times. It was the perfect pen for both men and women, and we think it still is today. Our new “JR” model, introduced as part of our revival of the Esterbrook brand and added to our core line of collections, is stylish and refined without being too fancy. It’s meant to match your style, as nicely as it graces your hand. With an elegant design, that isn’t fussy, it is compact in size, so you can always have one on hand and with you on the go, wherever you go.

How do I fill a fountain pen with ink?
It depends on the pen's filling mechanism, which you can find in the Technical Specs section above.
Here's a quick definition of the most common filling mechanisms:
Cartridge - A small, disposable, sealed plastic reservoir that holds fountain pen ink. These come pre-filled with ink, and typically you just push to insert them into place and you'll be ready to write!
Converter - A detachable and refillable ink reservoir that allows you to use bottled ink in a cartridge-accepting pen. Typically you will install the converter into the grip section, dip the nib/feed into the ink, and twist or pull the converter knob to draw ink into the converter. Here's a video for how to fill a cartridge/converter pen using a LAMY pen as an example.
Eyedropper - A pen that utilizes the entire barrel as a reservoir for ink. Ink is directly filled into the barrel, allowing for a high ink capacity. Here's a video on how to do it!
Piston - A type of filling system that uses a retracting plunger inside a sealed tube to draw ink into a pen. They are typically either twist or push-operated. These pens cannot accept cartridges or a converter, and only fill from bottled ink.
Vacuum - A push-style piston that uses pressure to fill the large pen body with ink. They seal the ink chamber when closed, making it ideal for flying without risk of leaking.

How do I clean a fountain pen?
It depends on the filling mechanism, but it mostly comes down to flushing it out with water, and sometimes a little bit of Pen Flush if the ink is really stuck.
It's a bit easier to show than to tell, so we've put together a few quick videos showing you the process:
How often do I need to clean my fountain pen?
We recommend a good cleaning every 2 weeks, and any time you change ink colors.
Water will usually do the trick, but we recommend you use our Goulet Pen Flush if the ink has been left in the pen for a while and could have dried up, or when you’re switching ink colors.
My pen won’t write! What do I do?
First things first... make sure you have ink in the pen! Be sure that the ink cartridge or converter is seated properly in the pen, and that you aren't out of ink.
We always recommend you give your pen a good cleaning first, using our Goulet Pen Flush, or a drop of dish soap in some water. New pens often have some machining oil residue left in the feed, so a good cleaning often does the trick first.
If that still doesn't work, try priming the feed. This consists of either dipping your pen nib and feed in ink, or forcing ink from the converter down into the feed.
If it’s still not working after that, please reach out to us so we can help!
