Can someone point me in the right direction for refills? I've bought several based on the recommendations and none fit!

If you search for this PEN-NITE-NTP31 you will find it with several replacements to choose from.

can you put a space pen refill in this?

This pen uses the standard Parker-style refill. As long as the FIsher refill has the Parker adapter it will work

where is pen manufactured?

Well since Nitecore is a Chinese company, I’m assuming China. I don’t have the original box so that’s my guess.

Will the refill black-p900-fine tip schmidt parker style ballpoint refill work in this pen?

I believe that’s the same as a Parker refill so yes. I did have an issue with the bolt action though. Due to the aluminum body, it wore out quickly and wouldn’t stay open
