## Description

Product Description S.T. Dupont ballpoint pen refill. Suitable for Defi and Liberte Collections. Box Contains 2 x refills

Review: Branded refill came quickly - Does exactly what I wanted, a branded refill that writes well and does what it is supposed to.
Review: Doesn't fit my model - 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 desertcart UK at the same time fit perfectly. So, this beautiful pen still has some life.

### ⭐ Poor quality
*by D***A on 21 December 2023*

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