Working Ink is part of FWG and we’ve spun it off so we can that we can sell our Function Links. Now Inks are just Inks with a function. And the first function that we’ve come up with is Conduction. It’s an old carbon ink that’s very safe and it has an amazing conductivity.

  • Hi Mr Robert

    I’ve been following you for a few years in YouTube.
    I would like to buy some of your inks.
    Can you please advise or provide the link?
    Oh, I’ve discovered that dried mushrooms are a great souerce. I do not have the materials to carbonize it as I am in Luxembourg working and it’s very hard to find a house here.
    If you could try it (and used coffee powder) I would be very interested to see your views on the type of carbon you would get..

    Kind regards
