Yep - and only realised that once I had eyedroppered it (the cartridge converter doesn't screw tight enough and leaks ink inside the barrel). But it was easy to take the feed and nib out and rotate them to fit the section,
and, for now at least, it doesn't drip.I spoke too fast. It drips, massively. So I'll try your advice and heatset the section with boiling water , fingers crossed but I can't carry that amount of ink in a pen that does that to me !
Maybe I've misunderstood something in this thread but just to say that I've put Noodler's flex and Omniflex (arrgh) nib in the Himalaya V2 (acrylic) with no problem. Had the Omniflex been less scratchy and, well, horrible, it would have been great. The feed on the Himalaya V2 is just pure magic.
I'll still make sure I carry this eyedropper nib up at all times...
As a side note - the tine eyedropper that came for free with the Him V2 is lovely to write with (was hoping I could swap the nibs with the Kaweco but no)
I wish you all the best with re-heat-setting the grip section - I found I could (and needed to) use scalding hot water for maximum effect.
I had some problems with the piston filler / converter mechanism leaking too, at least at first. It was readily resolved, though, by unscrewing it and applying some silicone grease to the threads.
The Muft pens are generally quite nice to write with. My only complaint with them (as with a lot of cheap eyedropper pens) is that the lid is not really airtight, so over time the ink in the reservoir will slowly evaporate. Best not to leave the pen lying around for too long...
