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

We used these for favors at birthday party. Worked great and kids loved them!

I highly recommend this product. So many pens for a great price. My kids lose everything. Now I have backups. I love it because it kept them busy for a while! They still enjoy it

The kids were excited about the pens. I like that came in individual packs which made very nice to hand out. And they actually last.

Gave these out at my daughter's school for her birthday! The kids adored them. Luckily the box had more than 20 because about 5 of the blacklights didn't work. If they all worked I would've given 5 stars because they are pretty magical with a beautiful invisible writing pen tip and wonderful black light. Who doesn't like writing & receiving secret messages?

My 7 year old son used these as part of his Valentines Day card treats for his classmates. The extras we kept at home all worked well and he has had a ton of fun writing secret messages and decoding them with the light. I would definitely purchase again!

I buy these every year as my meet the teacher gift to the students! They are always a hit and these are super affordable!!!

I bought this as a gift at the end of 4th grade for my students, so they could continue to write their own stories, even if they didn’t want anyone else to read them yet. I can’t speak for the ink, but the kids loved the invisible ink pens.

I bought these invisible ink pens to give to my 4th grade students for Valentine’s Day. They are so fun! I think the kids will love them. I will definitely be buying more of these in the future.

It’s literally invisible ink, WHO WOULDN’T BUY THESE 🤣 it’s like the silliest thing ever to write something and know no one else can see it then use your special pen to light it up for a quick 😱😱😱 from friends. It actually never gets old 🤣 even adults would want this just as a keepsake.Ink is great, light is bright and has good coverage of area but it’s not that strong, you’ll have to hold it about 10cm/4 inches away from the surface you write on but I’m almost 70% sure this ink would work under any black light. 🤷🏾‍♀️The people I gave it to with my party favours are fascinated with it and were all 20+ 🤣 good for adults and kids alike, just appreciated differently 🫶🏽 I’d definitely buy again.

Well made and super coolArrived in a cute package

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

We gave this pens on the surprise bags at the end of my 9yo bday party. The kids were thrilled! Huge success. My kid spends hours writing secret messages and making hidden drawings show in the light.

Good product for adding into kids birthday treat bags, was used for a kids party (4-5 year olds)
