Penventory, a Vault for Fountain-Pen People

Why it surfaced

Penventory treats a fountain-pen collection like an archival system: it records nib grinds and fill levels, builds digital ink swatches, calculates display-tray valuations, and connects real cases to NFC stickers or QR labels. It is an unusually specific answer to the question of where, exactly, all those pens are.

A collection-management tool for cataloging fountain pens, nibs, inks, trays, cases, and their physical labels.
