S.T. Dupont Medium Rollerball Refill - Blue (Pack of 2)

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 Amazon UK. Thanks.

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.

I ordered the ink refill and they arrived genuine and on time. Recommended seller. No issues at all.

Great nice quick delivery

This looks identical to the refill already in the pen, in the picture, the left hand one is my refill, the right hand one is the replacement, unfortunately the nib is too big to fit in the pen, so wasted my money. The number on the side of the refill in the pen was 306. It was a black ink. The one I'm reviewing has 711 on it, blue ink. If only this was in the description!

As described.
