The Penventory

Penventory is a comprehensive catalogue for fountain pen collectors. Log pens, loose nibs and inks, with the detail a collector actually keeps track of and none of the spreadsheet. Every pen holds its nib size and material, filling system, chassis and trim, release year, limited edition number, where it came from, what you paid, and up to twelve photographs. Your vault syncs with thepenventory.com on the same account, so it is on your phone at a pen show and on your laptop at home.
