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.

Fun overload!!! Seriously but these. Perfect for spelling homework or secret notes.

This is a great gift for kids and it works well.

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.

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!

These pens are awesome! Me and my 7 yr old love that we can write secret messages to each other and only read them because we have a “magic pen”. I will be purchasing more for her class to put in party bags with a mini notepad. Super cute gift idea and works as expected

I needed 23 for my sons classroom since they hand out little gifts to classmates to celebrate their birthday. I wanted to give something fun for 5-6 yr olds and not a crap toy that would not get used. This was amazing so kids could practice writing as well as do secret messages. I also ordered top secret notepads to go along with the pens. I got so many comments from the parents that their kid loved the pen and loved that it wasn’t a cheap toy they would pitch.

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

Well made and super cool Arrived in a cute package

This was the perfect Valentine gift for my kids to share with their class! What really made it special was how much my kids loved the idea! They were thrilled with the fun, unique twist on their cards. I highly recommend this for anyone looking for a creative, non-chocolate option! -The best part is that the pen is invisible, so there’s no mess at all

There’s were a HUGE hit for our son’s birthday! They work great and they were perfect for birthday gift bags

Was okay for the most part but a few pens were broken.

I got these invisible ink pens for my daughter's birthday party goody bags, and they were a perfect choice! All the kids had a blast writing secret messages and using the UV lights to reveal them. It added a fun and creative twist to the party, and the kids couldn’t get enough of it. The pens worked great, came in fun colors, and were super easy to use. A great value for the price and definitely something different from the usual party favors.
