Great Invisible Ink Pens with Built-In Decoder (UV Light)

For the price, these invisible ink pens are perfect gifts for kids. I'm planning a treasure hunt for my nieces/nephew and needed a good way to write "secret clues" that they could easily decode with the built-in UV light. The pens aren't extremely durable but they do the trick just fine. The kids will love them. They work well, and the writing is pretty easy to read using the UV light on the cap of each pen. The ink is invisible in a few seconds after it dries. I'd recommend.

Check for loose batteries in the cover!

2 worked, 2 didnt. Not a big deal, going to return and buy another set because the kids like them. But definitely disappointing since they were in their Easter baskets and they wanted to use them right away and one set didn't work at all. Should have tested it before. May 16, 2017 EDIT** The seller MALEDEN contacted me and shipped me more pens to try out. We tested them and for some reason only the blue ones gave us trouble. We took the little tabs out and pressed the light button down in different variations. We thought they were faulty. UNTIL! My daughter unscrewed the cover and found the batteries were loose and put them in proper and PRESTO! They were working great! SO DOUBLE CHECK THE BATTERIES IN COVER!

Great fun and good value...

This were a big hit with my grandchildren as stocking stuffer type gifts on Christmas. I bought them for four 7-11 year old boys but ended up giving the extras to the teenagers. I thought they might be packaged as sets, but each pen was in a separate package, so I had plenty. They work well and the quality is fine for a toy. Delivery was typically fast Amazon service. Recommend.

My Kid Won Halloween This Year With These

My daughter has reached the age where schools don't allow much in the way of holiday celebrations. Being avid Halloween fans, I opted to make treat bags for her class. Being in 3rd grade, I wanted something a bit more sophisticated than tiny bubbles or plastic vampire teeth. Her entire class went wild for these! And given the quantity for the price, this is a definite winner.

Dissapointing gift!!!

I bought these for my son's birthday he loves these type of pens and a kid at school stole the ones he bought from the school store. So I bought these. Unfortunately I had to play with the batteries one is pretty dim and 2 are just about dried out. So for the price I hope he can get a little use out of it. Update: The manufacturer contacted me and sent out 16 replacement pens. They were prompt with a response and I wasn't expecting that. Customer service is excellent!!

This is a great product, the kids love it

This is a great product, the kids love it. They are playing mystery adventures and writing clues for each other and using the light to decode them. So happy that we found this. Thanks

Entertainment for hours

My daughter and her cousins have these and they write little secret notes back and forth. They love them and the light being attached is a big bonus since they wont loose it or fight over it. The ink isn't colored like i thought it would be but its hasn't detracted from their fun at all.

Perfect for numbering rsvps

Got these to number my rsvps for my wedding. That way if anyone forget to write their name I'll know who it's from with a simple run over of the light! Of the pack of 4 I only opened the one and it works perfectly!!!

Great gift for Kids, Teens and Adults!

Well packed and organized. The product is really good. I bought this to gift my kids friends and teachers at school for Valentines day. I'm eagerly waiting to get the feedback from them. I have ordered another pack. Thank you for the awesome product.
