GIFTINBOX Invisible Ink Pen, 28PCS Spy Pen with UV Light for Kids, Birthday Party Favors for Kids 4-8 8-12, Classroom Prize for Students Magic Marker for Secret Message

I am a second-grade teacher, and I bought these for my classroom for students to write weekly words and check each other's work. I also used them to write the answers to math problems and posted them around the room. Students could use their pens to go around and check their work, which they loved. The lights were very bright and were easy to use. They were very cute and functional for my classroom. The students were excited to use them, and they were pretty durable because they were able to last, and they got to take them home at the end of the school year.

Really great for kids parties and playing detective! The pens write well and the ink glows better than expected under black light. We bought a bunch of black light flashlights for the kids to use and they really enjoyed "looking for clues." Lots of fun and a great price!

I gave these to my littles ones classmates at the end of the school year. They were a huge hit for 1st graders!

How many kids do you think love glow in a dark stuff as long as the parent knows what it is and the child does as well. This is a perfect gift to have loads of fun with secret messages so forth and all.

Bought for a birthday party. The kids loved them. Loved that it was invisible until the black light lol.

These were a hit for our glow day at school! They worked great and are easy for kids to use.

Kids love it

Perfect to put into birthday goodie bags, unique and the kids all had so much fun with them. Also doesnt leave a mess anywhere
