Awesome set for the price!by Michael,Top Contributor: Baby (5 out of 5 stars)

These worked great for an "escape room" I made for my church youth group. The lights are all the same and can be used interchangeably. I does dry pretty invisibly unless you go too heavy with the ink. Some papers are also better for this than others so try before your final draft. I printed a black and white design that had lots of tight lines and then I used these pens on top of the design. The design made sure the invisible writing was undetectable.
It worked perfect! I hid a bunch of flashlights including the UV ones. The piece of paper with the hidden clue also had Luke 8:17 written on it (For nothing is hidden that will not be made manifest, nor is anything secret that will not be known and come to light.). The teens realized that the UV lights were different ("hey, these lights are purple, weird"). It still took them a while to figure it out. In fact, they shined the regular flashlights through the pieces of paper and couldn't see the invisible writing. Seeing their "Eureka" moment was pretty cool.
They're not perfect. They're not junk, but they're pretty cheaply made. Blue and yellow look exactly the same under the black lights.
But they worked great. I do suggest them for an inexpensive option with multiple lights and two usable colors! I see someone else didn't get lights, but I got mine March 30 2017 and mine had 3 pens and 3 lights just like the picture (Sold by Directglow and Fulfilled by Amazon).
I'm using it on a painted surface and it's much better than the Nissen UV paint marker in those area

The ink, especially the red & blue (surprisingly) is very fluorescent under UV, doesn't smear, dries fast, and is highly invisible under ordinary light. I'm using it on a painted surface and it's much better than the Nissen UV paint marker in those areas. Unfortunately the yellow one seems to have a manufacturing defect in that the ink end pulls off much easier than the cap does. As a result I'm now covered in conveniently invisible ink.
These work

I used these to write secret messages for a DIY escape room. When used on white printer paper, the ink disappears without a trace. I found that it did not work so well with colored Post It notes... I could see the writing a bit when examining it closely. So, depending on your writing surface, these may or may not work for you.
Red is useless. The others are okay.

Fades after ~1 day. Red one is useless, not even barely visible. Needs to have a blacklight directly pointing at it at a very close distance to be visible. Blue is most visible and is actually useful and works well. Yellow is also good but the tip is a lot thinner than the blue one. Again if you are getting this just assume that you will be throwing the red one away as it's impossible to see without pointing at it directly with a blacklight lamp/flashlight. It won't work in blacklight lit rooms.

The items we received do not function as pictured in the photo. I bought this item because I thought the UV ink would "glow" red, or green or blue or yellow. Like in the photo displayed. They do not. It is standard normal UV ink, so don't let the misleading photo get you.
Also only two of the three pens worked, the non-working pen does not "glow" the ink goes on the page like water but does nothing when you put the UV light on it.
At least it wasn't much money.
Fun UV light markers

We used these for an escape room we created for our church youth group, and they worked fine. The yellow one isn't as strong/bright as the other two colors, but we learned that the yellow one is actually the best if you are hiding your writing on white paper because the others leave a little bit more of a visible mark. The flashlight that comes with the set is very small (keychain size) but it works perfectly well. Overall we had a great time and would use them again.
Blue and Red work great. Yellow not so much.

Red and blue worked fine, good colors, great response to uv lights. The yellow started yellow and turned blue....had to use a regular highlighter to get yellow into the design. Red marker kep separating in the back, had to use small pliers to hold base to remove cap.
Work well, but aren't going to last long

I used these to create an escape room. The clues I made were hard to read at first, but were bright and easy to read by the time we did the escape room later that night. The tips of the markets frayed after using them just for this activity, which will make them hard to use again because they don't write precisely anymore.
Worked as expected

These are great! The writing easily showed up under a black light. I didn't realize they came with flashlights, so I'd bought other ones- I was glad I did, anyway, because the included flashlights are prettty flimsy and lame. But the markers are great and overall I was very pleased!
Served their purpose

Bought these for a school project for the kids. We made them work for what we needed them for, but 1 of the pens was broken when the set arrived. They are pretty cheaply made, but they do work under a black light so they served their purpose.
