Jinhao x450 and x750 Fountain Pen Nib Swapping

If you have a Jinhao X450 or X750, you can greatly increase the versatility of the pen by swapping out the nib with a variety of available #6 size nibs. In fact, it was because of this feature that Jinhao really got on my radar in the first place. It all stemmed from conversations going on about which pens would fit a Goulet nib.


When I developed Goulet #6 size nibs I'd done so mainly to allow pen fans to swap out the Noodler's Ahab flex nibs for conventional ones. For a while this was a great fix, but now the Noodler's Ahab doens't work with our Goulet Nibs. I also knew that there would be a variety of other pens that you could fit with the Goulet nibs, and Jinhao was one brand that people started talking about as a part of that conversation. I hadn't had any personal experience with the brand at that time, but I put it on my mental watch list. It wasn't until a couple of months ago that Jinhao resurfaced and grabbed my attention again, and upon purchasing a variety of their pens, I saw what the buzz was all about. They're solid pens, and the nibs are good…but limited. I knew there was a great opportunity here to marry the Jinhao pen and Goulet nib.

So in the spirit of education geared towards the tinkering pen enthusiast, I recorded this video to instruct you how to swap a Goulet nib (or any other #6 size nib you have handy) with your Jinhao X450 or X750. Both of these particular pens have the same nib/feed setup, so they will not only write similarly out of the box but they'll also both take a replacement #6 nib equally well. When swapping, you can do it either dry or inked up, just be aware if you do it inked up you're practically guaranteeing yourself some inky fingers!

Doing the actual swap is pretty straightforward. The nib and feed are friction fit in the pen and there is a positive stop to keep it from going in too far. The nib housing is cut to fit the nib and feed exactly, so it practically orients them properly without you having to do anything special as long as you stick them in the right way.

So if you choose to upgrade your nib to a Goulet one (which I'm very obviously affiliated with and am promoting unabashed here), you can do so inexpensively for a solid pen (with converter) and a German-made JoWo nib. By all standards, that ain't too bad! The writing enthusiast in me is jumping up and down at the ability to swap nibs on yet another one of my pens. I love love love being able to do this.
