S Te Dupont 40770 Ballpoint Pen Refill, Oil-Based, Medium Point, Blue

When the previous cartridge in my S.T. Dupont Fidelio ball-point pen went dry, I went searching for a replacement cartridge that would fit my pen. The old cartridge didn't have any identifying number on it; so I was flying in the blind at the beginning of my search. I just had to find a cartridge somewhere that looked like the old one. The D-40851 cartridge looked like the previous one but I still wasn't sure. I ordered it anyway since I had few other options. I was delighted when I received the cartridge and it fit perfectly in my pen. So, it was a perfect fit and that made me a very happy and satisfied customer! I can use my pen again!

Ok

This was an authentic ST Dupont refill, just as I like - the point and the color

If you want genuine parts then this is the spot. Buy with confidence because they sell the “Real McCoy” here boys and girls!

When it arrived it was bent

As described

It's a genuine refill.. thanks

You can't beat the real thing for Dupont pens. The best.
