3M Scotch 311DC Heavy Duty 1-Inch Mounting Squares, 48 Squares (2 Sets)

I used these to attach a whiteboard to my fridge, which has a slight curve. I stuck them on the back of the board, added magnets, and it held perfectly in place! I love that they come in small square shapes—they’re super versatile. They also work great for homemade cards to add dimension and make artwork pop. Super handy and easy to use!

I am putting these under figurines so that if they get humped they won't break. The ones that have the hooks just aren't strong enough for this use. These work great.

These are a repeat purchase. Although these might seem pricey, the value is in that you do not have to hang a poster or something similar with them more than once. They stay put! My college office and the walls adjacent to it is constructed of concrete blocks, so there's no thought of nailing anything anywhere, and "Command Strips" have not worked for me for hanging posters, concert programs and other notices. I can always count on these and make sure I have some on hand in case I need to put something else on my door, wall or just outside my office. Terrific product, so convenient to purchase here.

It seems hard to remove from what I have tried.

Great for holding framed pictures level. Put one on each of the bottom corners of a framed picture and it will remain level when it is dusted.

These stick fine, endure, and come off.

Not the same product as advertised in the photos, but seems like a similar thing. So far it holds decently. I haven’t used anything heavy duty but am holding up a couple pounds with each square.

This is a somewhat permanent adhesive pad. You will have to scrape it off with a tool to remove. I cleaned both surfaces with alcohol and let dry, peeled the backer off one side and applied to object I was attaching and then peeled the backer off the remaining side and aligned with my mounting location and then pressed firmly. Get it right the first time, there is no redo. Once it is stuck, it is stuck.
