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 honour the four noble Houses of Hogwarts. From the courageous lion of Gryffindor to the wise raven of Ravenclaw, 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.

But no journey is complete without its magical counterpart. Each Joule is complemented by its original House ink—a gleaming 38ml treasure crowned with a sculpted metal cap, cast in intricate detail to bring each House mascot to life. These collectible bottles shimmer with brilliance and serve as timeless keepsakes—true emblems of distinction.
