The 4th and final edition, with 4 heart pieces #3776 Century Shape of Heart “Bluebird”. This series based on the concept of “someone’s happiness.” As the name suggests, the final edition will be delivered in a coloring inspired by the “Bluebird”, which is a symbol of happiness.

It features two heart-shaped pieces created when punching out the breather hole in the nib, placed in a transparent dome on the pen’s finial with zirconia crystals. While the heart-shaped cutouts are normally melted down and put back into making more nibs, the Shape of Heart fountain pen incorporates them into a pen’s design.
