    This is the best product ever that I really like, because it has the perfect quality and best features, it is real, you can write anything you want and it looks like invisible, but the best of it you can show what you written by targeting the blue light, I really love this product !!!!

    Pros: - nice materrial - good made - unrecongnised - very thin - nice for jokes and for fun cons: - when you write, the ink is invissible put the pencil makes some shadows on the paper so you need to pe very careful when you write something because it can be read if you press on the paper

    funny, nice to have

    It is working and the kids love it. But the battery time is very short, 10-15 minutes and the 3 battery's is dead. Seems that the switch has a lose connection in one of them. But when it works it is very fun :-)

    Funciona de verdade, é barata e prática. Muito bom para fazer anotações em livros durante estudos sem estragá-los.

    Impression:Very impressive!;
