Fendi Mon Tresor entered the record around 2017: compact bucket with drawstring top and dual straps for shoulder or crossbody wear, in calfskin, ff-embossed and canvas editions, with drawstring stoppers, engraved fittings hardware and the drawstring.
The little bucket that arrived at the mini-bag turn: shown September 2017 for Spring 2018, so guides split its birthday across the two years and the file records why.
The model has remained in the maison's catalog across eras; this file anchors on its documented history and makes no claims about current lineups or prices, which is why it reads the same in ten years.
The introduction is marked circa because the documentation is: fashion houses publish far less history than they manufacture, and the file records the range the evidence supports rather than inventing precision.
The full collector's file for this model, era details, and the authentication walk-through are on the writing schedule; the record above is permanent.
Fendi does not encode dates, but it brackets them: bags before 1980 carry no serial, the serial era runs 15 to 17 characters on leather with the first six naming the model and none of it naming a year, the hologram sticker era runs 2004 to 2010, and the sewn RFID pouch takes over from 2010, with 2015 the one changeover year where both markings can legitimately coexist. A hologram and an RFID pouch together in any other year is the classic fake tell, a pouch with no chip inside is another, and the era the markings claim must agree with the model's own documented birthday, which is what the serial era guide on this site checks in one step.
Model histories and date-code systems compiled from documented maison history, resale-industry authentication references, and period documentation, cross-checked across independent sources.
