ASR Tactical Invisible Ink Pen Secret Formula Disappearing Blue Gel Ink Pen

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.

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.

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

You have to heat the writing up for it to disapear

First pen did not write at all unless tapped on desk several times, and then only for about one inch of writing before needing to tap it again several times. Replacement pen better, but still not like a regular pen. Must hold it vertically and write slowly or ink will skip. Very awkward to use but the ink does disappear within a few hours.

It’s hard to say that the ink disappears when it never appeared in the first place. The pen I got sucks and can barely write.

This is a gre

It doesn't work at all I tried it but it doesn't write at all
