If you, like many, are currently renting your humble abode, you've probably thought about dressing up your walls —

And then immediately declined when you thought about the big holes you'd have to repair before you move. (#Worst.)

Well, push that fear aside, friends! According to our buddy, John Gidding, you CAN hang big and heavy wall art in your apartment — without using a SINGLE nail or hammer!

All you need is this little gadget — a High & Mighty Wall Hanger.

Get this: There are five different sizes to choose from — from 20-pound hangers to 125-pound hangers (the larger ones boast a built-in level) — and all you have to do to install it is push it into your sheetrock wall.

Seriously, that's it. Just place and PUSH!

And the best part? "If you're in a rental unit and you don't want to hurt your walls, they pull right off and they leave just a tiny little hole," says Gidding. Which means an easy patch-up — WIN!

Watch the video above to see John and Rach demonstrate just how ridiculously easy it is to use these!
