## Description

Product Description S.T. Dupont Rollerball pen refill. Suitable for Olympio, Defi, Liberte, Neo-Classique Large, Classique 2, D.Link/Caprice Fidelio, Ellipsis, Monteparnasse and Gatsby Collections Box Contains 2 x refills

Review: Fits and writes perfectly - Very pleased the refill fits my 30 year-old Dupont. The pen was called a rollerball “convertible” as it also could be used with felt tip, and as a ballpoint with a special adapter plug to fit the lower pen barrel. Haven’t been able to find the correct ballpoint refill, yet, either from Dupont, Parker or Schmidt (any reader suggestions would be welcome). But at least I can now use it as a rollerball. The ink has a very smooth flow. I bought both blue and black refills. Though I now live in Canada, excellent standard delivery from desertcart UK. Thanks.
Review: Product Consistency - The quality of the cartridges varies massively, in the same package I had one cartridge write very smoothly and last ages, the next one wrote very scratchy and barely lasted a week before the ink became start-stop on the page. The price is good and when they work well they’re great, the consistency towards quality is dissapointing.
