Platinum Preppy Fountain Pen

The Platinum Preppy is one of those pens that belongs in every collection — whether you're picking up your first fountain pen or you've been writing with them for years. It's lightweight, smooth, and comes ready to write with a cartridge already included.

The cap features Platinum's "Slip and Seal" mechanism — when you close it, the nib seats into a spring-loaded interior cone that creates an airtight seal. The snap-fit cap closes with a satisfying click so you know it's secure. That seal means the Preppy can sit unused for months and still write immediately when you pick it up again.

The translucent barrel lets you see your ink level, and the barrel color matches the ink inside. Pink, Red, Green, Blue, and Violet each come with matching ink. Both Black and Clear come with black ink.  The colored clip matches the barrel on every version.

Choose your nib based on how you like your line — the 02 Extra Fine for precise, delicate writing; the 03 Fine for everyday versatility; or the 05 Medium for a bolder, fuller line. New to cartridge installation? We have step-by-step videos on Instagram and TikTok.
