The Platinum #3776 Century Black Diamond is a new take on the original with rhodium trim and a dark black translucent cap and barrel.
 
The Century line features the innovative, patented-pending “Slip & Seal” inner cap mechanism that prevents the ink from drying out in the nib for up to 24 month
 
Includes cartridge and converter.
 
Platinum's nibs are remarkably consistent, offering moderate ink flow and a smooth writing sensation.
