## Description

Product description

Review: 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.
Review: 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!!
