Help with pin headers

Using previous advice here I managed to assemble a piantor and soldered the microcontroller on the pcb directly and I have to say that for a complete beginner that was very challenging.

I've gotten 5 pairs of PCBs and I kind of destroyed one pair but I am still trying to assemble at least another keyboard so I have a backup as I reckon it would take me a few days to be able to be proficient again on a non ortholinear keyboard now.

So I decided to try to use the female pin headers to be able to remove the microcontroller if I ever need to in case it dies or something of the sort.

I had the regular pin headers already and I know I can remove the pins from the white strip so I was going to solder them into the pcb while attached to the female and cut the extra length they'd have.

I got this specific female ones from Aliexpress https://www.aliexpress.com/item/1005005053790061.html I got the ones named "1x40P Female Tin"

When they arrived however, I ended up noticing that the regular pin headers I have do not fit the female ones. I have no idea what to search for to buy just the pins and what dimensions I'd need to get them, can anyone please advise me on what's the name of the loose pins and which ones should I buy please.

Thanks in advance, thanks to this community I have a working kb now :)
