It works
Used this in a student project with our robotics class to create an “escape room”. We used it on a blackboard in a dark area, with some text written in chalk and the other text with this pen. It worked great.

Yellow is great - don’t get blue version
Yellow works as advertised. Blue however is visible even without black light and identical to yellow when under black light

Exactly what I was looking for
Work great ! You can’t see anything without the light. Exactly what I was looking for. Note that if you want the design to really pop you should do atleast 2 layers

Works but not truly invisible
I make a lot of DIY escape rooms. This pen reacts well, but isn't truly invisible. I needed something where I could highlight words against a white background. If you paid attention, you could easily make out the places where the writing was. If you're just looking for something that really stands out under black light, this works great!
