Welcome to a special “I took these photographs at the hotel at World Horror Con” edition of Fountain Pen Friday. Considering how much I love the Pilot Petit1 Mini Fountain Pen I decided to give the Platinum Preppy (Jet Pens, Goulet Pens, Amazon) a whirl when I ordered a bunch of stuff recently.
I really enjoy using this pen. It’s been my daily carry since I started using it.
It’s definitely a full-size pen, but it writes with the same ease and fine line that the Petit1 pens do.
I bought a fine nib and it writes with a very nice narrow line that is absolutely no problem in smaller spaces.
Good news for those who do eyedrop conversions, this pen is PERFECT for them. Because it is a larger pen it will hold a ton of ink. There’s an added o-ring as per: this tutorial, but holy cow this thing would hold a massive amount of ink. I may make this pen my first eyedrop conversion after I write out the cartridge.
The Good
- Good-looking plastic pen
- eyedrop convertible
- round grip
- secure snap on cap for traveling
- Cheap (Just over $3 at Jet Pens, just under $4 at Goulet Pens, Amazon pricing terrible)
- writes nice.
- writes FAST
The Bad
- hard grip
- proprietary cartridge
- While not heavy, it is not as light as the Petit1 (because it is larger)
Overall grade: A
The Petit1 still remains my favorite, but this one is RIGHT UP THERE and I reserve the right to change my mind if it is a superior eyedrop conversion.

My only problem with these is that the barrel invariably cracks if I leave it in my purse, usually around the cap collar, so I then can’t cap them anymore–the plastic is just too brittle. Otherwise I love them! Haven’t tried the conversion, but I do refill and reuse cartridges.
