Today I was at the store and I needed a pen. A particular box caught my eye and as I read the package, I felt compelled to buy this thing just to see how gimmicky it was.

"This thing" is the Pilot FriXion gel pen.

It's no gimmick.

This is a gel pen with perfectly legit blue gel ink, a smooth writing action, and a comfortable shape.....

And it's 100% erasable. I mean, CLEAN erasing with no residue, and basically no trace of ever having written anything. If you pressed hard when you wrote, you can still see the actual indent from the tip, but other than that - ink is GONE.

It works via heat from friction. The "eraser" is hard rubber and doesn't flake off on the page like normal soft erasers. You rub the ink, heat it up, and it turns perfectly invisible. It's AWESOME. I've been drawing unnecessary lines all day just so I can erase them.

Just don't sign any legal documents with them, cause I think getting the documents warm might make the whole thing disappear :)
