Beta K

Hi people!

I’ve found that thing on the net.

I would like to know from which the metal pen is. I could not find anything about it, but perhaps it has maybe someone.
Or you know what metal can write?

I’ve tried it with a little alu rod which I have sanded, it works but the line is very thin and not so visible.
