Kids had a great time! Can still see the ink initially, have to let it dry a bit to be "invisible".

Fades a little bit, but works pretty good! Now I can write secret messages in my journal.. not very bright when in natural light, but pretty vibrant when it's dark. (As shown in the second image, taken during the daytime)

We made an escape room for Christmas and used the black light pens to write out some clues. It made it so fun!

I like the functionality of the pens. They work for message writing only. They're fun to use.The drawbacks I found are as follows:Marker quality was not what I expected. The yellow didn't stay yellow when applied. It was yellow for a few minutes and then it turned blue. The blue had a thicker point so the strokes were broader. However, the blue was vibrant and the red was also.Bottom line; they would be great for secret purposes and not the artistic project I had in mind.

These do what you would expect. The markers leave their invisible mark and the black lights, although not very bright, make the marker show up.The colors are very faintly different as far as what color they are when you write on something. We found the yellow to be the easiest to see and what we ended up using for our project. We wrote on playing cards and the ink did seem to dry and stay for our purposes. If the surface was more slick I don't know if we would have had the same results.
