About PencilDB
PencilDB is a database of mechanical pencils, ballpoint pens, fountain pens and inks. We build it together, and we correct it together. ■ Point the camera, and the pen identifies itself Move the camera slowly toward the part number printed on the barrel. PencilDB reads the marking and looks it up. Recognition happens entirely on your device. The photo itself never leaves your iPhone. ■ Keep a record, one pen at a time Sort pens into "Owned" and "Wanted". Add what you paid, when you bought it, where from, and what condition it is in — as much or as little as you feel like. Every one of those fields can be left empty. ■ Used prices come into view Once two or more people have reported what they paid for a part number, the price it actually changes hands for starts to appear. While only one report exists, no figure is shown. Otherwise what you paid would become "the market price" all by itself. ■ Straight to a shop that sells it For each part number, the shops selling it today are listed with their prices. Links that earn us a commission are marked as ads. ■ Know the company behind the brand Company profiles for 64 brands, with every model they make. Founding year, country, and what they have built over the years. ■ Articles Barrel materials, nib widths, the stories behind the brands — written for people who are serious about pens. ■ What is in it now 2,854 models, 12,460 part numbers, 64 brands. Sailor / Montblanc / Pilot / Mitsubishi Pencil (uni) / Platinum / LAMY / Zebra / Pentel / Faber-Castell / Caran d'Ache / Kuretake / Kaweco / Visconti / Montegrappa / Eboya / WANCHER and more. Everything comes from the manufacturers' own price revision documents and official sites. Each entry records where it came from. ■ A nickname, a password and an email address. Nothing else. No real name, no street address. The only thing shown publicly is your nickname. The email address exists so you can reset a forgotten password; it never appears on screen. ■ Corrected by everyone Found a mistake? Anyone can submit a correction, photos included. A person reviews them before they go live. Once two people are friends, they can message each other. Anyone you would rather not hear from can be blocked, and problems can be reported. ―――――― Site https://www.pencildb.com Terms https://www.pencildb.com/terms Privacy https://www.pencildb.com/privacy
