Platinum Procyon fountain pen: a minimalist design with striking finishes. The porcelain white finish provides a ceramic feel to the sturdy aluminum body and cap. The innovative feed mechanism only requires the nib to be submerged up to the breather hole when filling with bottled ink. Platinum's patented "Slip and Seal" cap design keeps the nib from drying out for a year or longer without use. The pen’s new nib design has a pentagonal profile, which gives it flex for responsive writing.
