Cute
Super cute and fun stocking stuffer for the kids for Christmas. They esp love using the little light for many things besides just seeing their writing. Pens work well and dry quickly and they liked the bright colors.

Invisible with normal light, works great with black light! Love them!!!
These are great! We used them to label the back of each wedding RSVP with a number so we could figure out who it was from - in case of hard to read lettering and/or they don’t say who it is. Once the ink dries I couldn’t even see it! And with the light provided it was easy to see! Highly recommend if you want an invisible ink pen that’s at a great price!!

Worked perfectly for my RSVPs
These worked well to number my ivory wedding RSVPs. And I actually got to use them once as someone did send back an RSVP without a name! I tested these on several types of paper and discovered that they don’t work as well on darker papers, the markings are faint, but still visible if you are looking or paying attention. But on light paper, you couldn’t tell at all!

So much fun!
These are so much better than the pens with the big light on the end of them. They are very inconspicuous and they write in each represented color. Lots of fun for kids and adults. The lights can hang on a keychain. They are exactly like the lights that show blue light filter on glasses. It’s difficult to see the blue a yellow through my camera phone but believe me they are true to color.

Pink didn't work??
When I got the product everything was going well until I opened the pink one and it did not work!! I was kinda disappointed because it took a veryyy long time to get it. The blue and yellow colors look the exact same but it's not a big deal. But for 9 dollars is really good! It's not to expensive but not to cheap, the quality for a pen for 9 dollars is pretty dang good. The flashlight's durability is really fragile and cheap. The pens are really high quality!! I don't really understand how or why the pink didn't work and I'm still sad about it but I would probably buy this again! :D
