Scotch Removable Double-Sided Mounting Squares, 16 Pre-Cut Foam Squares, 0.7 in. x 0.7 in., Removes Easily Without Leaving Any Residue, Photo-Safe, Mess-Free Application (108AMS-SQ-16)

Super adhesive! I use four for my huge posters, but honestly i could get away with just using two! A bit of a hassle to remove, and i wouldnt recommended using these unless you have a plan on where you want your posters to be because these mounters STICK! I love them!

These small double sided adhesive squares worked well to affix magnetic snowman pieces to my apartment door, which is not metal. They were easy to apply, held well, and were easy to remove after the holiday. They did not damage the paint on the door.

These Scotch mounting squares are great for mounting lightweight things like posters, signs, etc on walls. They're a removable alternative to the permanent double sided tape offered by 3M. I've used these on all sorts of items and typically you can remove them without a problem but I will note a couple of considerations: First if you put these on paper, you'll probably not be able to get them off. Laminated paper or smooth surfaces is no problem though. Next, if you cut them smaller, they don't hold together as well. These are not like double sided tape where the foam is consistent throughout the product. It's like two sticky sides with an open cell foam between them. The edge of the square is the area where the two sides are joined together. So cutting the square weakens the integrity of the foam structure. Finally, if you leave them on a surface for a long time (months and months) they might leave a sticky residue behind. This easily comes off if you rub it with your finger. I use these a lot and those are my only items of note. They are of the expected 3M quality (top notch).

As with most every Scotch product, these performed perfectly: exactly as advertised and expected. Used them to hold a plastic 3 AA battery box to a painted house door. Was in place for about 6 weeks, and exposed to warm and cold temperatures. Stuck very well, yet no problem removing from either surface when I wanted to take it down. Perfect.

I used to love these! The original gray version was absolutely perfect—super easy to use, strong, and reliable. But unfortunately, they changed the product, and the new version is a huge disappointment. These newer ones are incredibly difficult to work with. The backing paper is so hard to peel off that I actually had to stop after trying to hang just a few papers—my arms were getting sore from the struggle. It’s such a frustrating experience for something that should be quick and simple. It honestly feels like the adhesive is fighting me every step of the way. Please bring back the original version! The older gray ones worked beautifully, and these are just not usable for anyone who values their time—or their muscles. Until they switch back, I won’t be repurchasing.

I know these are removeable but the adhesive is so weak they were pretty much useless

I used to use the ones that were bigger and had foam in between the sticky sides. I thought that that was what I was ordering when I got these ones instead. I admit I was skeptical at first, but these ones work great!

This is a great product, for posting lightweight things to the wall. I love that they are removable, and reusable, and they do not leave any residue on your wall, or whatever you are putting on the wall. I would buy these again.
