.At the heart of the Houses of Hogwarts™ collection lies the most enchanting duo— where writing becomes a ritual, and every detail leaves a legacy. 

The Joule Fountain Pen, Ferris Wheel Press’ crowning achievement in writing design, has been transformed to honor the four noble Houses of Hogwarts. Each edition features a custom-etched grip section inspired by House iconography and virtues. Precision-crafted with a solid brass body and finished in radiant House- themed lacquers, the Joule delivers a beautifully weighted writing experience with exceptional balance in hand.

Each Joule has a matching House ink (not included)— a gleaming 38ml treasure crowned with a sculpted metal cap, cast in intricate detail to bring each House mascot to life. The ink is sold separately.

Each pen also comes with a pen sleeve.

Note: Due to the metal threads on the cap, we strongly recommend not posting the cap to avoid scratching the pen body.
