APPLAB 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.

Love these magnets, but need two squares per item to hold up my wood laser cut design on the refrigerator.

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.

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.

I've been using these for refrigerator magnets. They are perfect to hold pictures/paper on the refrigerator. I'm not sure how they would work with heavier items. I like that they are square and they dont move around like round magnets do. I like how thin they are. You can cut them smaller with scissors.
