Have you ever gotten some adhesive on your card where you don't want it?
How about sticking over the edge onto the next piece in plain view?
Good heavens I do this kind of thing all the time.
Xyron Adhesive Eraser to the rescue!
Now I'm not saying it's going to remove every adhesive all the time.
But it sure does a bang up job on my tape runner adhesives.
Just rub it over the adhesive you want to remove and Ta Da it picks it up.
I've had mine forever and I still use it all the time.
