    Ela é bacana para mim, pois posso deixar mensagens ocultas só para quem eu quero que veja... e tb uso ela para desenhar ou detalhar algum desenho, isso dá um efeito legal. O ruim é que a ponta dela suja rápido, então é necessário um cuidado maior.

    Invisible Ink Pens are pretty cool, you feel like Bond.. James Bond when you use them and you can leave secret notes on the fridge (what are the chances someone would think theres a secret message under the fridge sticky note message "get milk, bread") unless you let it slip theres virtually no a...

    - Writes on many surfaces, including skin and wood! - I wrote on my door three days ago and it's still there, even though a little less bright. - Comes with it's own battery!

The UV LED works well to illuminate the ink The ink is faintly visible enabling it to be read, some colours of paper make it The... Read more

Good for kids and Adults. if you push to hard down on the tip it will go inside the pen and you are unable to get it out. When the ink runs out there is no way to re fill... Read more
