    you can make notes on paper and use the light to remind yourself about it. Also would be a good study method

    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 :-)

    I'm impressed how easy it works! The writing is really invisible unil you light up the writening with the UV-LED. It's easy to hide an additional message in a letter. Maybe really more than just a toy!

    Impression:Very impressive!;

    Pros: Works as advertised. Nice fun. Cons: - Came pre-installed with 3 battery's however these were already depleted. :(( Luckily there were 3 spare battery's I could use. - You can read what is written due to the indention the pen leaves in the paper.

    Nice spypen - toy for kids

    Impression:works;

    It works great. The pen comes with batteries installed as well as three extra batteries. It writes easily like a normal pen but the "ink" is very light. The light that reveals the ink is bright and it works even in bright rooms. You can read what is written due to the indention the pen... Read more

    Very nice, works as described, really looks fancy. It is not heavy, and the ink goes easy in any surface. Works on paper, skin, and so on. The material is not that great, but it does not matter as it is for fun only A friend will use to paint people's faces and when the party is on, he will turn... Read more
