Box of six blue fountain pen cartridges. For the following pens: Olympia, Defy, Liberty, Néo-classique, Classic 2, D.Link/Caprice, Fidelio, Ellipsis, Line D, Mon Dupont.

Review: Fakes - Like the previous reviewer, I ordered two boxes and there's no way they fit a Dupont Lady, despite the white label stuck on the box. That label covered the indication of the types of pen for which cartridges are suited on a real Dupont cartridge box (which reads Montparnasse/Lady/Gatsby in silver letters). I lifted this label: there's nothing underneath. These are fake.

## Questions & Answers

**Q: Will this fit a dupont fidelio olympio fountain pen?**
A: Yes. It did fit mine. But I bought my pen in the late 1990s, so not sure the newer ones are exactly the same. Although I think they are likely all the same to keep from changing the cartridges.

**Q: Size of refill**
A: 1.57 x1.77 x 0.31 in.

**Q: how many cartridges are in the order?**
A: 4
