Warner Bros. | Harry Potter | The Joule Fountain Pen | Ravenclaw House

Description

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 accompanied 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.

Care Instructions

• DO NOT post the cap onto your pen when writing. Our pen has been designed and balanced to write with the cap un-posted
• The threads of the cap are brass and risk damaging the lacquer if you post the cap
• Store pen vertically with the tip pointing upwards when not in use to minimize clogs; routine flushing and maintenance recommended, especially with sparkling inks

Filling/Changing Ink Colours:

• Clean by unscrewing the barrel from the grip section to access the converter.
• Place the fountain pen nib fully into warm water. Flush the nib by twisting/untwisting the converter until the water runs clear.
• Allow to dry thoroughly.
• Fill a new colour by fully submerging the nib and feeder into the ink, then draw the ink into your pen but twisting the converter until you’ve reached the top position.

Notes:

• For heavily saturated inks and darker tones, or clogged nibs, you may need to soak the nib/grip in water overnight
• It is normal for some air bubbles to enter the converter when refilling ink
