craftgrrl | Oh, Magic Gluey Stuff

There's a magic substance out there in the world somewhere, but I don't know what it's called or where to find it and I want it.

It is a rubbery kind of stuff that sticks credit cards to paper or cardstock, advertisements to the cover of phone books and those are the main ways I've seen it used.

The cards and ads come cleanly away from it and it can be pulled off the surface of whatever it's put on. When you pull it off it is kind of stretchy and looks like a booger.

I want some, but I don't know what I should be asking for. The closest thing I've seen to it are Glue Dots, but those look like they are for permanent attachments.

All ideas, musings, etc. are extremely welcome. Thanks!
