Self Contained System For Writing and Reading Secret Messages

I bought a set of these markers for ten bucks in October 2017 and you just cannot beat the value. With 12 in the bag, you can easily host a kid’s birthday party, treasure hunt, or classroom activity complete with invisible ink clues!

So good I bought them twice!

Is there a child in the world who doesn’t like the idea of sending secret messages in invisible ink? If there is, I haven’t met one yet. These pens will be a hit with any child who can write and who enjoys making up their own games. It’s the simplest thing but it really is fun. These would be a treat for kids who like secret spy games, crime-solving or super-hero games, for those who like passing secret notes or leaving clues that only certain people can see. Write notes with these pens and the words disappear almost immediately. But there is a special UV light at the other end of these pens. Anyone who has one of these can shine that light on the page where the invisible message was written and – voilà! – the message appears! I think these would make brilliant party favors or Valentines Day gifts. I’ll bet teachers could find lots of ways to use them in the classroom and they’d also make terrific end-of-the-school-year gifts to encourage kids to practice handwriting and spelling over the summer.

We had good results drawing on black paper with neon crayons or …

We bought three packages of these for a science/art session with a mixed 1st-3rd grade class. They were inexpensive enough to buy one for every student and were a huge hit. One package had two pens with completely dead batteries, and another package arrived with one pen separated from its cap and completely dried out, so you may want to leave yourself some leeway and order extra if you need a certain minimum number (the failure rate on our order was 3/36). Also, if one doesn’t light right out of the package, try twisting the end of the cap a little; on a couple of ours, the press button on the cap wasn’t lining up properly with the switch. The button batteries are replaceable by popping off the end of the cap.

Fantastic pens!

My kids love these pens, they work really well. My kids drew on themselves and no one got a rash. They drew on the walls and there is only one spot where the writing is visible, it must have something to do with the way the sunlight falls in that part of the room. I cleaned it off easily with a wet, soapy cloth, no problem. I will definitely buy these again.

BIG HIT!!! 😊

These pens were perfect for my detective theme! I gave these pens to my kids at our open house and they were a hit! I wrote their names in the invisible ink then showed them how to shine the light to reveal their names. They were AMAZED! Thank you!

So fun!! For all!

Ten stars! I got two packs of these for my kids and nieces and nephews as part of their Christmas. We all drew on each other all Christmas Eve night. They LOVED them and honestly, so do my husband and I. We kept the black ones for ourselves and made it a game to leave each other notes before our day starts. Finding our hidden notes is the perfect start to the day..

What fun!

Although we got these pens as a treat for grandkids, we did check one out to see if it “worked”. The kids will love them! Write on anything (including skin) and it doesn’t look like anything happened. Shine the light attached to the pen on what you wrote – magic – you can see it. Perfect for a stocking stuffer, or a treat bag at a birthday party – or to hand out for Halloween even.

Im a grown adult and I like um! LOL

These pens are pretty awesome. They came on time and were exactly as expected. You write in clear ink and then the lil light on top “reveals: the message. I got these as party favors for my kids bday and I’m pretty sure they’ll be a hit with kids of all ages cause I like umm too! lol I will try to update with pics and the kiddos thoughts soon. I gotta say though-for the price I think they’re cool and worth it 🙂

Playful colors, bright light and good invisible ink.

These are awesome invisible ink pen markers. I use them for EDU breakouts and fun activities with high school students and my young nieces and nephews. So far they all work, and the ink is clearly visible.

It worked better than I thought

It worked better than I thought. When I was younger invisible pens were more “invisible”, because you could still see the indents on the paper. These are more like quick dry markers. No evidence on the paper. I had bought 2 packs for a birthday party, and one had a problem with the cap. But since we ended up not handing out all of them this wasn’t an issue
