Invisible Spy Ink Pen 5 PCS, With UV Pen Light, Party Favors for Kids 8-12, Stocking Stuffers for Christmas, provide Thanksgiving, Halloween for Boys Girls Goodie Bag

These were great and very cute, used them for an escape room game I planned for some friends and it was nice to have both the light and the pen in one. Also, in a dark room this was an impressively bright light for such a small package, could illuminate writing on our high ceiling and still be legible.

PERFECT!!!! Low price makes it even better. These are similar to a dry erase type of ink, great for what I need it for. Not as bulky as a normal pen even with the uv light attached to it. Easy to use, writes smoothly, and dries quickly. Cap is on extra tight so you won't lose it.

Used these to write numbers on my RSVP cards and they worked really well. They wrote just like any marker. Definitely glad I bought them.

These were a lot of fun for our kids. You write with them and then use the light to see what you wrote. The only complaint i would have was that the ink did not last that long in the pens. But, given the price...I cannot complain. The boys loved them and had a blast sending each other secret notes!

I bought this for my 10-year-old nephew it's his first time going to sleepaway camp. I kept two for myself to be able to decode the messages. These pens work amazing!!!! Super easy for a 10-year-old to use! I will definitely buy this brand again!!! I literally got Best Aunt of the Year Award with this inexpensive, super cool gift. :)I hope my review helps you!

My kids loved that this pen was invisible until you used the light on the back. The pen is functional for fun! It was a good value for the money. It would make a great little gift in a prize bag or a goodybag of some sort.

I use these to send secret messages to my nieces and nephews so much fun. Let’s bring the secret Dcoder pens back.

I bought them for a light up mat I have . Not brilliant for that purpose because you have to hold the button down for them to light
