The Platinum 3776 Shape of Heart Fountain Pen - Black transforms one of the most overlooked components of a fountain pen into the centerpiece of its design. While the exterior presents a refined and understated black resin finish accented by rose gold trim, the true story lies within. The Shape of Heart collection celebrates the craftsmanship hidden inside Platinum's nib manufacturing process, incorporating the delicate heart-shaped cutouts removed during the production of the brand's renowned 14-karat gold nibs.

What began as a functional byproduct of manufacturing has become a meaningful design element and a tribute to the artisans behind every Platinum fountain pen. By preserving and showcasing these tiny gold hearts within the cap finial, Platinum offers enthusiasts a rare glimpse into the often unseen details that contribute to the creation of a world-class writing instrument.

Craftsmanship & Design

The Shape of Heart Black pairs polished black resin with warm rose gold-plated appointments, creating a sophisticated aesthetic that balances contemporary elegance with traditional Japanese restraint. The contrast between the deep black body and the softer metallic accents gives the pen a refined character that feels equally appropriate in professional settings and personal collections.

The defining feature of the collection resides within the transparent cap finial, where the gold heart-shaped punch-outs generated during nib production are carefully preserved and displayed. These miniature components are not decorative imitations but genuine pieces created during the manufacturing of Platinum's gold nibs. Their inclusion creates a tangible connection between the finished writing instrument and the craftsmanship required to produce it.

Enthusiasts often appreciate the Shape of Heart series because it celebrates a detail that would normally remain hidden forever. Rather than focusing solely on external decoration, Platinum draws attention to the precision and artistry involved in creating one of the most important components of any fountain pen.

Writing Experience

The Platinum 3776 Shape of Heart Fountain Pen - Black is fitted with the same 14-karat gold nib that has made the 3776 Century one of Japan's most respected modern fountain pens. Known for its precise writing characteristics, controlled ink flow, and responsive feel on paper, the nib offers a distinctly Japanese writing experience that emphasizes accuracy and consistency.

The pen's balanced proportions and comfortable section make it particularly well suited for extended writing sessions, while Platinum's proprietary Slip & Seal cap mechanism helps prevent ink from drying out, even after prolonged periods of inactivity. This innovation has become one of the defining features of the 3776 Century platform, allowing writers to enjoy reliable performance without constant maintenance.

Collectors frequently regard the 3776 Century as one of the finest values in gold-nib fountain pens, admired for combining exceptional writing performance with thoughtful engineering and enduring reliability.

Brand Heritage

Founded in Tokyo in 1919, Platinum Pen Co. has spent more than a century refining the art of Japanese writing instruments. The company's commitment to precision manufacturing, practical innovation, and writing performance has earned it a devoted following among enthusiasts around the world.

The 3776 collection takes its name from the height of Mount Fuji in meters and represents Platinum's vision of the ideal fountain pen. The Shape of Heart series builds upon that foundation by celebrating the human craftsmanship behind every nib, transforming an overlooked manufacturing detail into a meaningful design element. The result is a writing instrument that combines the proven performance of the 3776 Century with a unique story that resonates deeply with fountain pen enthusiasts.

Not compatible with eufy Omni C20.
Style: C20 Parts * 19pcs
The filters are too small. To avoid dust laden air from just going around them I put pieces of paper around the edges as spacers. But they're also shorter too. No chance of a reasonable seal. Then the vacuum bags are the wrong size too. The robot gives me an error message saying "no vacuum bag is detected". The mop still works, but no vacuum action. I only bought this kit because the one I was using (that works) was temporarily unavailable. Never again.
