Review: Perfect Fit & Works Great! - 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!
