The Chartres Blue Platinum 3776 Century is a contemporary fountain pen with a sleek design, comfortable writing balance, smooth flow, and fast-drying ink. The translucent blue body is accented by rhodium trim. The innovative cap contains a unique “Slip & Seal” mechanism that prevents ink from drying out in the pen for up to 2 years, while a newly redesigned 14k gold nib and feed regulate the ink flow. The attention to detail is also evident on the the cap ring, which has been etched to create a three-dimensional effect of the logo. The Platinum 3776 Century accepts proprietary Platinum cartridges or a Platinum converter for use with bottled ink. Only the cartridge is included, while converter and replacement cartridges can be found here. The Chartre Blue is inspired by the Chartre Cathedral in France, which is designated a World Heritage Site by UNESCO as it is considered to be "the high point of French Gothic art" and a "masterpiece". One of the most distinctive features of Chartres Cathedral is the stained glass, both for its quantity and quality.
