Description The Platinum 3776 fountain pen in Oshino with Rhodium Trim features a clear transparent resin barrel and cap accented by rhodium-plated trim. The Platinum 3776 fountain pen uses a rhodium-plated 14k gold nib that is available in several nib sizes and the pen fills via the included proprietary Platinum converter for use with bottled ink, or with Platinum cartridges as well. The cap of the Platinum 3776 fountain pen screws on to close, and the innovative cap "Slip & Seal" technology prevents the ink from drying out for up to 24 months! In commemoration of the launch of OSHINO fountain pen, it comes with a blotter card with a serial number for the initial 3,000 production lots. The back of the card may be also used as a blotter paper.
