Celebrating 15 years since the debut of the #3776 Century, a new model is bornrefined through meticulous redesigns in pursuit of even greater evolution.

The renowned Slip & Seal Mechanism, which prevents ink from drying out, now boasts enhanced airtightness, extending its effectiveness dramatically from about 2 years to over 3 years. In the Demonstrator model, the inner cap is printed to allow you to visually enjoy the moment when the nib is sealed.

The internal structure has also been refined: the inner surface has been made flat for greater transparency, reducing reflections and making ink levels easier to check. A rubber ring has been added to the section to further reinforce airtightness and prevent loosening during writing. With a newly re-engineered section structure, both strength and ease of maintenance are improved.

Through its clear body, the #3776 Century Demonstrator invites you to experience these innovations firsthand, offering a special writing experience where functional beauty meets transparency.

#3776 Century 2.0 Updates

The improved Slip & Seal Mechanism has extended the airtight performance from about two years to over three years, allowing you to enjoy fresh ink longer than ever before.

To improve visibility of the ink, the internal surface was redesigned to be flat, reducing reflections and making it easier to check remaining ink levels.

The rear section has been enhanced to improve airtightness, with a rubber ring added at the joint to reinforce the seal and prevent looseness during writing.

By revising the design of the Slip & Seal Mechanism, the nut previously visible inside the cap was removed, creating a clean, transparent space.

The grip structure has been redesigned, enhancing both durability and ease of maintenance, resulting in even more stable writing.

The nib engraving design has been renewed. The Mt.Fuji motif, inherited from the original #3776, has been refined into a contemporary expression, carrying forward its sense of trust and dignity while achieving a more polished and sophisticated look.
