Also included is its original Cartier red box, which shows a good general condition with light storage-related signs.

Overall, it is a very well-preserved fountain pen—elegant and perfectly functional, ideal for everyday use as well as for a collection.

Conservation recommendations

To preserve the pen in optimal condition, use high-quality inks specifically for fountain pens, avoiding pigmented inks or those with particles. If the pen will not be used for an extended period, it is advisable to clean it with lukewarm water, dry it properly before storing, and keep it in a dry place away from direct light and extreme temperatures. Also, gently operate the filling mechanism to maintain the mechanics in perfect condition over time.

It will be shipped in a courtesy box for proper preservation.

Happy bidding!
