The title highlights the brand, model, year, and the limited nature. The specific numbering (04642/25000) is an example: use it if it is readable on the bottom of your pen, as it reassures the buyer.

Key points for the description:

Conditions: the pen is used, without original box or warranty. There are signs of wear on the body (especially at the bottom) as visible in the photos.
Characteristics: state that it is a Montblanc limited edition “Writers Edition Agatha Christie” from 1993. Emphasize the black resin body and the 925 silver serpent clip with ruby eyes. Indicate the mechanism (twist ballpoint) and the serial number engraved (e.g. “No. 04642/25000”).
Contents of the sale: specify that the lot includes only the pen (potentially with cartridge/refill, if still available), without the original Montblanc presentation box or other accessories. If you have manuals or certificates, mention them; if not, be clear that they are missing.
Integrity: highlight that despite the visible wear, the pen is fully functional and authentic. Useful phrases: “used but original and functional,” “frontally intact, minor signs,” “Montblanc star logo firmly in place,” etc.
