Since its launch in 2007, the Platinum Preppy fountain pen series has grown in popularity among a wide range of age groups around the world. The all new Platinum Prefounte is a model designed more for adults that boasts a sense of high quality while retaining the basic functions of Preppy fountain pen. Subdued colors are employed for the transparent body made of resin. The graphics are also kept simple, while the metal clip adds an accent to produce a chic, translucent appearance ideal for adults. The stainless steel nib features a welded tip made of an abrasion-resistant special alloy, which provides an excellent writing feel.

The Prefounte fountain pen is equipped with Platinum's “Slip & Seal Mechanism” that prevents ink from drying out in the pen with the cap on for one year. It accepts proprietary Platinum ink cartridges (one blue-black cartridge is included) or a Platinum converter (sold separately) to fill with bottled ink.

For those who seek a smart and casual fountain pen, the Prefounte is ideal for both business and daily use, as well as for fountain pen beginners.

By converting this pen to an eyedropper, you can fill the entire barrel with ink for maximum ink capacity! All you need to do is add an o-ring and a small amount of silicone grease to the threads (available separately).

Wow!

For a cheap pen, this writes better than some of my $100+ pens. It's really smooth with no skips or hard starts. The slip and seal cap is a bonus allowing the pen to start right away. The converter is a must, but it's daylight robbery how much Platinum wants for it.

Great, affordable pen

Great daily writer with medium nib that is relatively smooth. I really liked that it came with Blue- Black ink rather than plain black.

I bought two of this pen. One several years ago when they first came out and another one recently in 2024. Both times it was the same experience. The pen would hard start almost every time uncapped and while writing. The first time the pen dried up completely after only a few weeks of being set aside. The second time I got so fed up with it I threw it away. I also bought a Procyon and a Desk Pen and they have ALL acted the same. The only Platinum pens I have ever had work for me are the Preppy. I really want a 3776 but there is no way I can risk this type of quality and experience with such an expensive pen.

Cheap pen, cheap thrills

I thought this pen was going to be better than what most were saying. It is not as enjoyable to write with as my Prera, Kakuno. this seems to write slower. I opened the tines and still not flowing very heavy. Maybe it is the cartridge and may need to fill the body up with ink, but I would be scared it might get crushed being a cheap plastic instead of a heavy resin or metal. And the converters are too expensive to buy separately which shocks me. My jinhaos come with a converter, why can't these for a low end pen? I am not extremely thrilled with this pen but will use it if I get a shimmering ink for a pen I don't mind if it gets clogged with pigmented ink. Time will tell.

Frequently Asked Questions

How do I fill this fountain pen from an ink cartridge? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

A cartridge is 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!

This pen uses proprietary Platinum ink cartridges, which are available in a few colors.

You can learn more about how to actually install an ink cartridge on our blog, or in this video tutorial:

How do I use a converter? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

A converter goes in the place of where the ink cartridge would normally go. From there, you can fill your fountain pen from bottled ink.

A converter is 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.

We have a great video showing how to use a converter here:

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

It mostly comes down to flushing out the pen with water, and sometimes a little bit of pen flush if the ink is really stuck. 

We put together a blog post with step-by-step instructions, or you can watch the video here:

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.

For even more information about fountain pen cleaning, check out our Fountain Pen 101 video blog post.
