The TWSBI GO is the most affordable TWSBI fountain pen yet! A unique feature of this model is the spring loaded piston. This resin pen has a clear body and clear grip section, so you can see your ink and the spring piston mechanism at work, and has a clipless push/snap cap. It is completed with a silver stainless steel nib.

It is incredibly easy to fill this pen from bottled ink - simply unscrew the barrel to access the plunger, submerge the pen’s nib down into the ink, press down on the piston to compress the spring, and it will fill the barrel with ink! Screw the barrel back on and you’re ready to write.

My new TWSBI GO

I am still new to the fountain pen world and this is my first TWSBI. I got the clear version because I wanted to see all the stuff inside. This one has the extra fine nib because I am looking for a daily writer for my planner and needed to write a little on the smaller side. For this, it works perfectly with the Diamine Polar Glow that I also purchased. The first thing you need to know is DO NOT plan on using the sample bottles to test or load this pen! It's simply too wide to fit into the typical sample sized bottles. Luckily I had bought the 50ml bottle of the Polar Glow, so I didn't have to find another way to fill it. This same width, along with the absence of a pocket clip will prevent it from being carried in a pocket. So far, that's about the only cons I have about this pen. It writes great. The cap snaps on and off easily and will post. It seems that the cap seals well enough to keep the nib from drying out fast, even after not being used for a week. So far I like it. But if you are still buying lots of samples to find out which inks you like the best, I think the Noodlers's flex might be a little better since it can be filled from the sample bottles.

Lovely pen but...

This is my first TWSBI and I like it very much BUT it is one pen that is hard to try samples from. Easy to fill with the spring contraption it uses but I don't like that you can't clean it very well as you can't really take it apart to clean the feed. Another little thing is that it skips sometimes and I still can't figure out why. Have had this pen for almost a 6 months and still skips from time to time. Very smooth when writing and comfortable in the hand.

Great pen...for my husband, darn it!

I have a mixed relationship with TWSBI. I love them, but sometimes the grip or weight isn't right for me. When this happens my husband is very happy to take them off my hands. The Go fills easily, has the smooth TWSBI writing experience, and belongs to my guy. The grip was a little too fat for comfort.

This is my new daily driver. I am unconcerned about it being list or stolen, as it is cheap, and the grip feels great. Also, nib is excellent for the cost.

Awesome and inexpensive

I use a fine-nib fountain pen for drawing and sketchbooking. Because it's difficult to really know a nib until you've tried it, I decided to try the TWSBI GO (with a broad nib) because it's inexpensive. Well, the quality's fabulous, and this nib works great on larger drawings.

FAQs about Fountain Pens

How do I fill a fountain pen with ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

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! Check out our quick guide here.
  • 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. Check out our video on how to use a vac filler here.

Check out more info on these filling mechanisms including a video on how to fill each one on our blog.

How do I clean a fountain pen? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

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? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

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? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

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!
