The Platinum Procyon is named after the brightest star in the constellation of Canis Minor, one of the first 21 magnitude stars. The pen employs an all-new body form following the concept of a fountain pen that brightens up people’s business scenes and lifestyles. Procyon fountain pens employ a "Slip & Seal Mechanism" that provides a smooth writing experience at any time. The body is made with aluminum to offer the best weight balance possible. The pentagon-shaped pen nib stimulates the pleasure of writing, while the special coating and lineup of vivid colors stimulate the pleasure of owning the pen.
