Got these for my kids school favors and they loved them. Kept some back for my own kids and they love writing secret messages on paper and on their skin and using the secret blue light to show me their messages. I prefer they didn’t write them on their face but that’s another story!! Love these! Side note: You have to buy little pads of paper to go with these if you are buying these as party favors!

Only one pen didnt light up. Kids loved these!

This was a great gifting idea. The kids loved it. I really liked how if was delivered in just a day

Bought these for my kids birthday to hand out in class at her school. Kindergarteners loved them. I tested all the lights and they worked.

Bought it for my son's, birthday favors. All the light and ink works properly!

These are great! My kids are obsessed with them, and we gave them as gifts for Valentine’s Day. Highly recommend.

Great party favors! Lasting fun. The kids loved these.

Kids of all ages are fascinated with this pen! Worth the money and makes a great gift!

Everyone was so excited to get these in their goodie bags for my daughter’s Spy theme birthday party!
