Magnetic Squares, 120 Pieces Magnet Squares (Each 20 x 20 x 2mm) on 4 Tape Sheets, with 3M Strong Adhesive Backing. Perfect for DIY, Art Projects, whiteboards & Fridge Organization (120 Pieces)

this one sticks. works on 3d prints. the others don't stick to the pla filament as good. I have used several hundred and have only had one come off. make your 3d print 2 mm thick. this drops the weight enough and still strong enough to be a fridge magnet. then just stick this on the back when done. this simple answer is better than more complicated options.

This is pretty ideal for small crafts. The package comes with three sheets of magnets. The magnets peeled off the wax backing very well—a little too well, in fact, as the first magnet peeled off the backing and promptly became stuck to another magnet. Fortunately, I was able to remove the stuck magnet and apply it to the back of a shatterproof travel mirror, as I intended. Unfortunately, when it comes to crafts, I’m all thumbs. Even though the magnet stuck to the mirror, it wasn’t applied quite straight. However, the adhesive on the back of the magnet proved too strong for me to be able to move the magnet after this application. With the knowledge of the bonding quality of the adhesive in mind, I carefully applied a sufficient number of magnets to the back of the mirror. I then stuck the magnet to the inside of a little metal case, which I turned i to a travel case for my safety razor. However, the magnets’ strength was insufficient to penetrate the case, which meant I couldn’t stick the tin on a metal plate. This is a bit of a blessing in disguise, as it means the tin won’t cause the other items in my dopp kit to become magnetized.

Great product. Adheres well and magnets work.

I bought this product to hang up decorations on a whiteboard in my classroom. The magnets are conveniently pre-cut, making the process quicker. The magnets are strong, I do use four magnets per piece of paper I hang up, mostly because the paper warps if I do not have one in each corner. The magnets adhere okay to the lamination, and VERY well to the whiteboard. It may be a little difficult to pry off from the whiteboard. They do not slide around, and there is no residue after removing. Will definitely purchase again for future uses.

These magnets are the BEST! I have been teaching for 15 years, and have tried many sticky magnets over the years. These are the strongest. There is strong glue on the back, so you dont have to worry about them separating from their attachments. I really do love these magnets, and you will too!

Strong enough adhesive to stick, while the magnets are strong enough to stick to the metal surface. plus there is a ton of them. works great on my husky metal workbench.

I glue 4 of these to hold up a boogie board writer (if you know what that is) to the fridge. A lot of these types of magnets are too weak, but not these. They suit my purpose. Not super strong like rare earth but good magnets just the same. Recommended.

The thickness, weight, and quality is just ok, These magnets aren't that very strong compared to other ones on the market and you can most likely use them for photos or notes on the fridge, but I wouldn't use these for much larger items as the hold capacity isn't that great.
