Works for an unlimited number of things. Making collectibles stationary and safe from falling over, putting up pictures. Whatever you can think of.
Love, love, love these. My primary use for these is in the car where I have several on the front of the dashboard. I use them mostly for holding my cell phone and sunglasses although I've also used them for holding my credit card or money when ordering at drive up windows instead of digging in my purse.
I have these in my car and i use them for sticking my kids tablet to the seats and my cell to the dash. Its very adhesive and easy to remove. Even when i hit bumps and all doesn't even move it one bit.
These are the stickiest of sticky mats ever to stick. Seriously, you could probably use them to peel wallpaper. I used the first few to attach my laptop to a lap desk, and I could turn the desk upside down or swing it in a circle without worrying about hurting the computer.
