    Some markers are more permanent than others I guess (I came across some that weren’t really bothered by isopropyl or solvent).

    For speed I’d suggest a stencil and some nasty spray paint (the type that isn’t easily removed).

      I can’t remember the name of them, but the pen was made of metal. Those never came off!

          I looked them up and they are pretty similar. I want to say that’s not them cause they aren’t exactly what I remember, but it probably is. I was a kid in a foreign land when I saw them, so who knows.
