There's so much you can do with this Vanishing Pen. The coolest thing is making it vanish in a tiny
plastic bag. That way you can see it until the last second...and you don't get ink on your hands.
But there are also cool ways to make it visually appear, which you can figure out by
playing around with it.
I had the old model vanishing pen for a while now...and that one
looses its shape a bit...the new model by SansMinds holds up great, though. Big fan of it.
