Invisible Ink Pens, Upgraded Spy Invisible Ink Pen with UV Light Magic Marker for Secret Message and Kids Christmas Goodies Bags Toy (7pcs)

These are cool writing tools. It comes in assorted colors. I bought to use for mystery puzzles & math. Pricing is great and it makes the perfect gift. Love the purchase

I bought these for an escape room I am planning for my chemistry students. I only need one pen but this multi pack was a better deal than just one. They write great and show up clear with the uv light.

Kids had so much fun with these. I love that the light switches on and they don’t have to hold a button down.

I didn’t use this as party favors, but it worked for a forensic science class! The quality was okay, what you would expect from the price, and the battery life is good. The button to turn on the light broke off on 1 or 2 of them but I was able to hold it in place. Good size, about the size of a crayon but thicker. They were pretty easy to use and write well!

Secret notes every where from my kids. Great entertainment

The media could not be loaded. Got these for my girls after I refused to buy one from the school book fair for $6.99. What a Scrooge I am… I know. But these are an incredibly awesome value. They function and perform just like the real deal. They are super easy to use and are great quality. Love that there were so many different color options—all three of my girls were more than happy and each got multiples. It’s been months, and we still use and get a kick out of them. Definitely would recommend them to anyone. Such a fun little pen/marker. My youngest is 5 and my oldest is 7. They all love them.

My daughter was so excited about these invisible pens she got for Christmas. Very neat!

Did buy for the kids as a party favor I knew they wouldn’t last so no I wouldn’t buy these long term
