Worked well for ettching
Works really well on silver

Not etch resistant, just a regular permanent marker.
Not etch resistant at all. It's just a regular permanent marker that could buy from any stationary shop. I have tried it several times with copper sulphate and salt in steel, but it dissolves in the solution long before the etching process has completed.

Just a regular marker
This is a regular permanent marker that you can buy from any stationers and cheaper, you can buy 10 on Amazon for less than £10. I use these for etching silver in ferric nitrate and they work ok, you can have varying results. Need to check from about 2 hours for design falling off and possibly cleanup peice redraw and etch again.

Misleading advert - not an etch resistant pen
Disappointing - this is a standard Staedtler permanent marker pen available elsewhere at a lower cost. It works as a marker pen but the ink is demonstrably NOT etch resistant.

It works.
Works but doesnt actually refer to being etch resistant, dont leave it in the ferric too long.
