S.T. Dupont Medium Ballpoint Defi Refill - Black (Pack of 2)

Does exactly what I wanted, a branded refill that writes well and does what it is supposed to.

The refill doesn’t fit my pen model. I have a 30 year-old Dupont that was called a “convertible” as it worked with rollerball, felt tip and ballpoint refills. The ballpoint needed a special plug adapter to fit inside the lower pen barrel- see the picture. The refill in the centre closest to the pen is the ordered ballpoint refill. The 2 refills to the left shows the correct refill with and without the plug. Clearly won’t work, top or bottom. I’ve only given 2 stars because I can’t find anything on Dupont websites that provides either a policy or a solution. I believe many of these ballpoint refills are based on the Parker P900, so I’ll just keep looking. Fortunately, the new rollerball refills that I ordered from Amazon UK at the same time fit perfectly. So, this beautiful pen still has some life.

This is not standard S.T. Dupont quality. The flow of ink is not smooth, and it dries for no reason. Do not buy.

i use some of them as they come,this product is just luxury on paper,it flows like nothing i ever encountered,they were so good i gave mine away to my friends as a great present.

good

The product leaks lots of ink that takes a lot of time to dry on the paper. Not up to Dupont standards.

not model specific - could only be made to work with an insert - check before buying.

Quite good
