Invisible Ink Pen with UV Light Secret Message Pen Spy Pens Magic Invisible Markers Classroom Gifts for Students, Party Favors for Kids 8-12, Goodie Bag Stuffers for Kids

These are so much fun for kids, and they work well.

Got as a Christmas gift for my son because he’s been telling me he wants an invisible ink pen and we’ve had so much fun ever since Christmas! We even write on our hand little messages to each other and then use the glowing part to reveal the message. He has shown other children and they’re impressed by these pens as well. Parents are asking me where I got them. They’re good quality, very durable, great value for the money since you get four. They are easy to use to use and they do dry quickly.

Worked well! Fun for me and the kids!

These pens are cute and fun to use; my kid sibling loved it. However, it dries out very, very fast. Also, we'd just been using two of these pens, and left the other two unopened for later (there are four pens in one package), but when we went to use the unopened pens a few months later, it did not seem to be working. The lights worked but the ink did not show up under the light. It's a cool product but for temporary use.

Fun for the grandkids!

I bought a bunch of these to give to a group of kids, and they were a total hit. The invisible ink and UV light bring back memories of old decoder pens—such a fun, clever concept. They’re easy to use, work well, and make a great little gift or classroom surprise.

I am not sure if it was the product or that my grandkids just were not interested, but I got these for them for stocking stuffers and they pretty much just put them aside. Maybe it was because they were overwhelmed with other more impressive gifts. But I still have not seen them use them.

Good item

I bought these as a replacement for one we got at the scholastic book fair. These are a great comparison to those ones and work just as well!

My kids loves them. We have been looking for them for a while, and of course amazon has them. excellent purchase.

These guys do exactly as advertised-I secretly use them daily...XD. They are also cute, and the light on each pen is very helpful.

These work great…still don’t think they are worth $10. Probably something you can find at Dollar Tree or somewhere but my daughter wanted them and sometimes convenience of delivery to your door is easier than shopping around.

Used the pens to write invisible clues for a Christmas themed scavenger hunt I prepared for my grandkids. Their little minds were blown once they saw how they worked. Fun was had by all. LOL: After the scavenger hunt; the grandkids may or may not have written invisible scatalogical words on their parents hands and arms.
