## Description

Need to leave a note for someone, but don't want to them to be able to show anyone else? The disappearing ink pen will allow you to do just that.This special formula was developed during the Cold War and is now encapsulated within the discreet gel pen for general use. Once on the paper, the ink will appear normally for about 15 minutes. Within an hour, the message will have completely vanished and will be unrecoverable; even with ultraviolet light.Note: deconstruction time of the ink will vary depending on ambient conditions.

Review: Terrible quality - Just got mine in the mail and it is TRASH lol. Not sure what I was expecting, but it barely writes in ink, just leaves a very faint ink line and immediately disappears. Would be kind of cool if it weren't for the tip being razor sharp, which leaves a very clear mark on the paper so you can see exactly what was there, ink or no ink. I threw it in the trash 2 minutes after opening it.
Review: Amazing pen, I went To Vegas and took out ... - Amazing pen, I went To Vegas and took out a huge loan with the casino, I used this pen to sign the loan and now I'm debt free. Don't feel to bad for the casino though folks, I lost it all trying to double it up on black in roulette.

- WATCH THE VIDEO: Once on paper, the ink appears fully legible and undiscernable from a normal pen for 15 minutes but slowly starts to disappear; fading within 20-30 minutes; completely after about an hour

### ⭐ Terrible quality

### ⭐⭐⭐⭐⭐ Amazing pen, I went To Vegas and took out ...
*by A***W on September 6, 2014*

Amazing pen, I went To Vegas and took out a huge loan with the casino, I used this pen to sign the loan and now I'm debt free. Don't feel to bad for the casino though folks, I lost it all trying to double it up on black in roulette.

### ⭐⭐⭐⭐ Dries up quick, but fun
*by E***S on June 18, 2026*

It’s really cool at first, and I used it to do magic tricks and pranks, but after a couple weeks, the ink dries out and it comes out of the pen invisible rather than coming out blue and turning invisible after a couple minutes
