- few minutes and everything is gone. Great gadget😊
- I would welcome the option of switching between ink that disappears and ink that stays like a classic pen.

Spy pen with disappearing ink. Let's conjure with this amazing Spy pen, which writes and draws with invisible ink. Try to imagine what it would be like to sign important documents, but your signature would disappear within an hour. If you think it is not possible you are wrong. We are introducing you the Spy pen 888 with the disappearing invisible ink. The ink has blue color, it looks like a classic pen refill, but this one is definitely special.
great pen
How long does it take for the ink from the pen to disappear? Thank you very much.
