I just moved. I'm not really fond of banging holes in my walls in the new townhouse, so I was looking for a way to hang some stuff without making ten thousand pounding noises and 5000 holes... and guess what? I found it. I'll admit, I was totally skeptical. Because well, its JUST double sided sticky tape right?
No... its SO much more than that. It adheres amazingly to anything smooth (chipped particleboard on the bottom of the shitty cabinets in the apartment no so much)
I've been able to hang large framed photos, canvas, even a few metal signs. And for the price, you get SO much. I dont even use it on all four corners. Just the top two, or for bigger pieces, straight across the top. And viola, instant hang.
