Children Kids Secret Message Invisible Ink LED Detector Lights Pens Ballpens

Great toy for the kids, especially little best friends who can read the 'secret' note. (Ink is clear. Use light built into pen to see what you are writing. Use the light to read it). They are going to have so much fun. Also great for diaries etc. A 'black light' torch could also be used to read if pen gets lost. The batteries in the pen (actually texta) can also be replaced :)

It's good. But the battery didn't last long. But that's okay because I can just get new ones. I just don't know how to put them in. Anyway. It is very good for the price.

My niece loved them knowing she can write in her journal with out having her lil brother reading her things 😉
