This pearlescent blue and green resin pocket-sized fountain pen is the Esterbrook JR, short for "J Reborn". Made from DiamondCast resin, it comes with gold-plated trim and a gold JoWo #5 stainless steel nib. A modern take on a vintage classic. It fills via standard international cartridge/converter (included).
We're dreaming of paradise. What better place to set our eyes on than Brazil? With its rich history, its beautiful coastline, and a culture dedicated to living life to the fullest, it's definitely somewhere we've been inspired by lately.
With this in mind, we're thrilled to announce our newest limited time release, the JR Beleza! Meaning "beauty", what better name for this vibrant addition to our JR collection? Made from DiamondCast, this pen has a luxurious sparkle to it that lives up to its name. New attention has been given to the JR line, which is a great pen option for those who are looking for a vintage-inspired, travel-friendly pen that's small but mighty. The “J” was Esterbrook’s sleek and suave, classic pocket pen that appealed to the practicality of the times. It was a perfect pen for both men and women, and we think it still is today. In celebration of these time-honored places, we’ve brewed up a little something of our own. Introducing the JR Pumpkin Latte. It’s our way to mix a little bit of our home state’s heritage with our morning cup of Joe.
The new “JR” is stylish and refined without being too fancy. It’s meant to match your style, as well as it graces your hand. With a refined design, that isn’t fussy, it is compact in size, so you can always have one on hand in your jeans or shirt pocket, purse, or briefcase. It can be 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!
