I suspect it is made by Tektra, which makes a lot of these products.

Hi chirath,

I don't know what Yamaha uses. But via a Google search for carbon conductive pen you should find something suitable:

Hope this helps!

Thank you for the replay.
Yes i did try this on google and i ordered " bare conductive " and it is not the correct one. the original ink looks like a graphite mixed ink and it is embedded ink.

I think these relative cheap carbon ink pens should be seen as an emergency solution (or for hobby projects). I believe that in industry special ink is used, which is thicker (less fluid) than the one used in pens. Maybe something like this -but is darn expensive and not easy to apply manually.
