SCStyle Invisible Ink Pen 7Pcs,Spy Pen Marker Kid Pens for Writing Secret Message Valentines Day Easter Day Halloween Christmas Birthday Party Bag Gift,Invisible Ink Pens with UV Light for Kids

This is one of my students favor treasure box prizes. I even use them to make goodie bags for the kids at the end of the year because they are so popular!

My daughter loved these so much that she drew on her face and there is definitely secret writing on the walls somewhere! We loved how many this pack came with

They work as advertised. Nothing super special to say. My son has fun leaving secret messages for us and his friends.

I am going to put these in my kids stockings for Christmas but I am glad I tested them out first. Two of them don’t work at all (the light will not turn on) but the others works great. Need quality check on these before they ship to customers.

Disclaimer: I got this for free from the vine program. I don't get paid for the review I just recieve the item for free. I try to base my reviews based on functionality, description provided, durability, and of course price.These are pretty cool for kids. Nice and simple. Not much else to say they come with a light so you can read the message.

I remember these pens, YEARS ago. They were fun for an hour and then the ink would show…or you could see the marks on the paper if you had light shine on paper. These pens are really invisible ink! We had a great time with scavenger hunt and “blank paper” clues. The old pens were the beginning. These pens are great! They work so well. Daughter tried putting lemon juice on paper to see if the note would be exposed. Tried simple bulb to see…tried water! It was very fun…and kids are adults! Imagine if I gave this to my pre teen nieces and nephews…wow! I recommend these pens simply for the fun of a creative game!

The is the second set of invisible ink pens that I've enjoyed. We had so much fun with them that we got these for my wife to give to her reading students as a reward.They're easy and simple to use and work well.The brightly colored pens (the casing) all write with the same "invisible ink". You can slightly see it when you're writing (think anything wet on paper), but as it dries it disappears. To see the message, simply turn on the UV (black) light that's on the end of each pen and you can see it as plain as day. The batteries are included (each pen has a little plastic battery saver tab you'll need to pull out, designed to prevent the batteries from discharging before you get them).I you want to bring a smile to a kids face, just bring these out. These are a recommend.

Invisible Ink Pen, Spy Pen Marker Kid Pens is not just fun for kids but for adults too. This set of seven pens were fun to use, making a time of fun for us. First, they were used for a mystery night where clues on paper then put around the room. What added feature they made for the solving of the pretend crime. Then the kids could use to wrote secret messages, etc.I thought perhaps that they would be like glow sticks that quickly lost their ability to work but so far that has not been the case. Here it is almost a month later, the ink and light are both still working fine.Not an expensive purchase but one that works, is easy to use and makes things interesting for children and adults. No instructions but it was easy for us to figure out how to pull the tab to start the battery for the light. That is standard on many items, not just these pens. I would purchase these.
