Invisible Ink Pen 24Pcs Spy Pen with UV Light Magic Marker Kid Pens for Secret Message and Birthday Party,Writing Secret Message for Easter Day Halloween Christmas Party Bag Gift

We put these and a little notebook in the stockings of kids at a family party and they were a HUGE hit. Kids of lots of ages LOVED being able to draw and write with their pen and then use the light on the back to see their secret design. The quality seems good, they were easy to use and held up to some "exuberant" use from younger kids. We were really pleased with these.

I purchased these pens for my kids birthday so he could pass them out to his class mates. The kids really enjoyed them and the durability of them is great. We had 1 pen light break but that was the only issue we had.

I bought these as little gifts for a class, and the kids were really excited about them. I kept one to use, and it worked exactly as described. I assume all the ones I gave away also worked correctly.

Used in toddler birthday gift bag, kids loved these. 2 didn’t work, Maybe batteries died, battery size is of course one that I don’t carry (tiny button-type).

Great for goodie bags or valentines!!

Bought these for a classroom party. They didn’t get here in time for the Christmas party so I saved them for Valentine’s Day. Over half of them do not work and now the return window has passed! The ones that work are a cute treat, but not worth it for only half to work.

These were a class favorite for Valentine’s Day. The kids had a blast with them and were easy to use.

For students. Fun science class
