The Platinum #3776 Century Demonstrator Fountain Pen is a high-quality writing instrument produced by Platinum, a well-respected Japanese pen manufacturer. Celebrating 15 years since the debut of the #3776 Century, a new model is born—refined 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. The Platinum #3776 Century fountain pen comes with a Platinum ink cartridge, a converter. This fountain pen features a 14k gold nib. 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. The #3776 Century is light and well-balanced for those long, uninterrupted writing sessions. Limited to just 2,000 units worldwide, this pen is sure to delight collectors and writing enthusiasts alike.
In 1919, Shunichi Nakata, started his fountain pen business that would later be known as Platinum Fountain Pen Co. The Japanese brand is closely related to the legendary Nakaya fountain pen brand, where some of the finest fountain pens in the world are created. This expertise also goes into Platinum's own line of fine writing instruments.

MantraOnline is the best place for buying fountain pens, accessories and stationery!
very good quality
I am mind blown by the sheer and well thought of design intricacies. Right from the retractable clip to the magnetic cap and balanced body to cap weight, the pen is a must have for all pen connoisseurs.
The pen writes flawlessly without any skips and is a wet writer.
Absolutely stunning!!!
The Leatherette Twelve Pen Case by Arista is a very beautifully made and high quality pen case. The case is robust and the partitions are well made and wide enough to hold all thick fountain pens. It's hard to find such a pen case at this price point and hence it's a very appropriate purchase.
The Pilot Metropolitan is the perfect first pen for any fountain pen beginner. I got this in M, and it writes very smooth. Will highly recommend the M nib for beginners. The pen came included with a converter, and I have been using the Parker Quink Black. Planning to order a wetter ink and mostly decided on the Pilot for this pen to increase the smoothness even more
