Invisible Ink Pen 24Pcs Spy Pen with UV Light Magic Marker Kid Pens for Secret Message and Birthday Party,Writing Secret Message for Easter Day Halloween Christmas Party Bag Gift

Great gift to do some games with kids (spionage games), good way to make them learn, to give them in birthday parties or last day school.

I purchased these as class gifts for my daughter to put in goodie bags for her classmates. I was looking for something different, and this was it. They came individually packaged...the light is part of the pen so you write a message and Shine the light to see it. The ink is quite visible and her friends had so much FUN writing to each other. The ink dries quickly so no worry about it smudging. They are a study quality and will hold up as well as any other pen.

The media could not be loaded. These things are great! My some brought these last year for his classmates for Valentine’s Day and even now, September 2025, the ones that don’t get given away are used! They write on skin, aren’t visible without the light and he loves them! We do all sorts of secret codes around the house and on various items (including our clothes) to keep the fun going. I like to leave him a message somewhere and a note (with a regular pen) that says I’ve left him a message somewhere and challenge him to find it. It gets him off his screens and gives him some excitement on a random day of the week! Get these and try something new! Your kids will love it! 🫶

The media could not be loaded. Used in toddler birthday gift bag, kids loved these. 2 didn’t work, Maybe batteries died, battery size is of course one that I don’t carry (tiny button-type).

I got these to put in my 7 year old daughter’s birthday goodie bags. They were the stand out hit! All the kids were playing with the invisible ink pens, even writing on each other. It works a great! Totally invisible until you shine the light. The ink doesn’t seem to last too long and in a couple days my kiddo’s ran dry, but she did use it a lot in those days. Highly recommend for kids party bags.

These were a great hit for my sons kindergarten class. The kids have so much fun. The size is great for little hands and they write great. No leakage and seems to be durable.

My students love the spy pens! The only complaint was about the little cartoons on them (for older students) Overall they loved them!

I was skeptical they would work and they do! Lots of "ink" and the kids love writing secret messages.
