It Works and stays on
I used this on metal surface and it applied and stayed on very well. Worth the money.

Great Loss Prevention Tool
This item enables us to covertly ensure a client who is claiming to have received unusable product too frequently is actually being honest and not defrauding us or our supplier

Doesn't Work on Paper
This marker does not work well on paper, works fine on plastic and cardboard.

Tip is too thick if writing smaller than 1”
Very thick tip makes it hard to write anything clear. It’s really bright initially but the brightness under UV faded more than I expected it to and although it does remain visible it remains a far cry from very clearly standing out.

Very visible, with uv ligt
Works great with Infray UV light. Opticz is bottom in pic.
G**T
Too runny and does not show up well.
The ink flow is too runny and once dried it does not show up well under a black light.

UV Pen Works Well
Just received this. I wrote with it on white paper and it worked just fine. **Only thing to consider when I used a different UV pen on colored paper, my "invisible" ink showed up a little bit. Consider than when you're writing on paper.
