GIFTINBOX Invisible Ink Pens with UV light for Kids, Spy Pen Party Favors for Kids 8-12, 12 Pack Invisible Ink Pen and Notebook, Magic Marker for Secret Message Birthday Party Favors for Kid 4-8

Kids loved it. Invisible ink works on regular paper too.

Bought box for kindergarten graduation goody bags & had a few leftovers for friends play dates. Big hit & 6 yr olds had/have so much fun drawing pictures & writing secret notes! Pens work on plain white paper when books are full.

This was a great value. All kids loved this product, pen size was perfect.

both my kids love these for party favors for age 6-10.

Ordered this set for my 6 year olds birthday. It comes with 24 pens and 24 pads. It’s a great goody bag stuffer/ stocking stuffer/ classroom exchange present. The ink is really invisible until the pen light illuminates the ink! So much fun.

Bought for 9 yr old party favors. Ink doesn't show without light, so that's a plus, since they want to draw on everything else. Have so many leftover, they're going in the Halloween bucket!

These were the biggest hit with ages 4-9!

My kids love this! Writing secret notes and passing on to each other to view under the blue lights is super fun for them. Gifted them as party favor to other kids and they all seems to work as intended and kids enjoyed the product. It’s worth it!

Gave these out as party favours for my 8 year old son’s birthday- they were a hit!

These were a perfect addition to my daughter's Unicorn-themed party loot bags. According to her, they were a hit, with all her friends bringing them to school the next day. My daughter personally enjoyed using it, especially for writing "secret messages" in her notebook. A delightful party favour success!

They worked great as party bag stuffers. They were perfect

My school was having a book fair and these types of pens were a very popular buy. I kept that in mind as I planned my end of year gifts for my class. Lo and behold, I came across this set of Invisible Ink Pens. I thought, excellent, my class will love this, so I purchased the set. I had a couple extra and was able to try them out with my nieces so I can say they work perfectly fine. I like the little spy activity books they added as well. It's little things like that you look for in sets like this.I handed out the gift bags and all the students immediately pulled out the pens to use. These are 6-7 year olds. It became a bit of a problem once half the class used them to put their names on their work so I had to start carrying my own light to figure out what belonged to who. I brought that on myself.I loved the variety of colours as well as the activity books. The only reason I took 1 star away was because the batteries did not last long at all. It's not a big deal because I know these types of batteries aren't great for longevity, but it's still something to mention. Outside of that, great purchase for my case study!

I bought these for my students. They loved them. They all worked, no malfunctions!
