Extreme marker. Worth every euro.
The review is about professional use.
It writes comfortably on any surface, covering anything else.

I bought it because it is refillable. I wrote a number on insulation tape and left it outside in the yard along with the marker. In a week, the number was barely visible and the marker didn't write.

Very good waterproof, I used it on the machine and it had 1-2 spots, I applied it again 2 times and it doesn't even show.
