Funny Magic Invisible Ink Disappearing Pen with Blue Ink Ball Point Vanishing in 1 Hour

This pen really works! It's a lot of fun. It's not very useful, but it's a fun gag gift!

it said that it would take an hour to disapear once you write something but it disapears as soon as you write it you dont even have time to read it before . what fun is that?

Works well! Ink begins to disappear after about an hour. Two hours later the ink is fully gone. Remember to write lightly!

Great pen, writes nicely but make sure you dont press down too hard and leave dents in the paper! The ink will disappear, but creases won't which can give away any pranks. Ink started really disappearing after ten minutes, and after around two or three hours left barely a trace, so keep in mind that it does take a decent amount of time. If you really scribble with it the paper will be a bit rough where the ink was.

Does not seem to work as well as I have hoped. The "ink" does not completely disappear even if you write very very softly.If you don't believe me, see the other Items I buy.. look at my profile. I'm a active buyer unlike some reviewers whom are from other companies just trying to "kill the competition". So yeah, when looking at reviewers... make sure you do pay attention to their profiles. Most of the fake reviewers you can tell by just looking at their profiles.

I was sceptic, I used it as joke on my kids for magic trick and really works. Within 60 min it was gone, like it was never there!

First pen leaked everywhere out of the box. Second one wouldn't disappear at all. Other reviews seemed mixed so I had some hopes. Didn't work out for me. I would not recommend these.

takes over an hour to disappear - not worth the $$$
