Platinum Curidas Fountain Pen - Prism Crystal
All the convenience of a click rollerball but with the smooth writing experience of a fountain pen: introducing the Platinum Curidas retractable fountain pen!
In five attractive colors, the Curidas is pushing the fountain pen world forward with its new design. With its translucent clear resin barrel, you can see all the engineering that went into the Curidas. Instead of a traditional cap, the Curidas uses an internal seal to protect the nib and keep the ink from evaporating when retracted into the pen. The steel nib is available in extra-fine, fine, and medium sizes.
Curidas is a coined term created by combining the Japanese word Kuridasu referring to extending the pen tip and the word Curiosity. This new fountain pen was brought to life to fulfill people’s curiosity.
It accepts proprietary Platinum ink cartridges (one blue-black cartridge is included) or a Platinum converter (also included) to fill with bottled ink. A special clip removal tool is also included if you prefer to remove the silver clip.

Customer Reviews
When the Curidas first came out, I didn’t like the look of it, and thought I’d see if an opaque one came out. When that happened, I got one with a medium nib, having not loved previous Platinum fine nibs.
In the mean time, I got very into Sailor pens and became a feedback snob. I also have a 3776 with a soft fine nib that was on rest after an ink mold incident. I pulled it out recently after months of non use and it wrote instantly. I was looking through my pens, and pulled out that Curidas. It also wrote instantly. But the Medium nib just wasn’t satisfying. I thought I’d try a fine, and decided to get one of the original plastic ones, and put the guts I liked best in the exterior I liked best. I assumed that would be the fine guts in the matte body.
When this pen arrived, I did indeed like the fine better. Better line and color fidelity to my tastes. To my surprise, I liked the look better, too. It has a fun sci-fi set prop feel to it, and all the chrome in the guts looks really good through the clear plastic.
It writes delightfully, more forgiving than other platinum nibs I’ve used, and has a surprising amount of bounce for a steel nib (as did the medium). The Platinum converter is simply the best converter out there, easy to maintain and works flawlessly every time.
And of course, as a retractable, and is so much more convenient.
It has its quirks. It has that odd clip set up, the enormous knock at the back, and disassembly is a little involved.
But It’s become my daily workhorse. I was ready to be disappointed, and was instead completely captured. This is the retractable to beat. My VP has gone into rest mode.
I see a lot of comments about the superiority of Pilot's VP. I'm not here to argue but a most important part of any pen is its nib and I like this one a lot. I use both sides - i.e. if the paper is poorer quality, I use the nib's inner side - both write really well and the latter even has a touch of an italic nib. For me this is a great pen.
I love this fountain pen with reservations. It is a little over priced for the issues i experienced. It writes well. I use it daily. If it is not in use, then the nib will dry out within two days but the ink in the cartridge remains fluid. I just moisten the nib and it returns to a normal ink flow with minimal effort. However, it is my second one of the same kind in a different color. I experienced a trial and error period with the first one. Sadly, the nib housing kept popping off. I took a chance and Gorilla glued it. The nib housing no longer pops off. I now have the perfect push button fountain pen. I do recommend it for daily use.
I write with F, EF I have one in each now ( one from Goulet ( green) i bought last fall- and another i bought from another company). I like to fill out small forms and use for 'tiny writing'. This pen is amazing. The flow with EF/F are dependent and wet, the line is precise, no skipping.One tiny tiny thing.. these are hard to find!I waited for more than a month to purchase get my second one. Sadly then it was defective one- (one post on the inner slot was made wrong)Sadly Goulet pens failed me.Covid was really spiking in my county and i didnt want to go into a postoffice. Goulet was slow to call, slow to contact ( maybe they were too busy) - all i wanted was a paid mailing label for the return in the exact box i recieved it in, and store credit.All in All it took an unacceptably long time ( over 6 weeks) to get this fiasco resolved- and in the end i never got what i wanted. I never got store credit. I never got a physical postage paid label- i had to go to the post office.. wait in line behind one person who took 20 minutes whilst a line of ten people and many people coming in the small no fresh air lobby, coughing, violating my six feet and many unmasked ( Montana is one of thise states the new governor recended the mask mandate) frightening. I am traumatized about the ' can't be bothered' rough customer service.
Great pen. Wonderful balance, writes very well, and will not dry out if it sits for a week. Great overall.
FAQs about Fountain Pens
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! 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?
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!
What's your return policy?
You can submit a return request within 30 days of your order date. You can read all our Return Policies here.
To initiate a return, please submit a request at the Return Portal. Our Customer Care team might reach out to you for more information.
Please note we are unable to accept a return of any Namiki or Sailor Bespoke fountain pen for any reason once it has been used with ink. Please thoroughly inspect and dry test the pen before use.
