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 :)

Very cool it took 2 months but good is what it touches This was my first opinion when I saw the product, but after trying it, my score is zero. I feel disappointed since he wrote his name and little else and I no longer saw anything, that is, dry wine or it simply is useless.

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.

Ha tardado 41 días en llegar a España. Exactamente como se describe, los niños quedaron muy muy contentos con el misterio de la tinta invisible. Lo recomiendo 100%
