Review: Works great - I don't really see a difference between the blue and yellow under the UV light (probably because it's blue) but the pink is very pronounced. Tried it on paper and faux leather so far and it takes a second to fade, but it isn't visible after it dries. On the paper, the pink marker left a very slight impression that you would not be able to see at a glance but if you look hard and know exactly where it is, you can see a small color difference. Haven't tested on other surfaces but so far, so good.

### ⭐⭐⭐⭐⭐ The Pros and the Cons (but mostly Pros)
*by R***. on June 11, 2025*

We did a scavenger hunt and this worked marvelously! We absolutely loved the invisible ink - it showed up so well! Pros: - The pens work great - The lights actually show the invisible ink. - That are durable and last well - They are just so fun!!! Cons: - The marker tips are on the thicker side so writing small is not an option. - The ink does run if it gets moist or wet. This is a great price for the awesome item you get - I would highly recommend purchasing it!
