MIKEDENeodymium Magnets, 5 Pack Black Super Strong Magnets Bar, Waterproof Heavy Duty Magnet with Adhesive Backing, Rare Earth Small Magnet Strips for Fridge, DIY, Craft, Science - 60x10x3 mm

Very strong. Tape could be a bit stronger but the magnets are solid. I replaced some tape with the 3m black roller tape.

Small, and VERY strong.

These are insanely strong magnets. They will even pull at each other from inches away. They did suit my purpose to have a foam board sign that's easy to hang and remove from a wire grid shelf for my booth. I only gave it 4 stars because they do have the ability to break which I've never seen a magnet do. I think it was when one piece attracted another and they slammed together pretty hard. Because I can't just snap it with my hands. You can see in my photo. Otherwise they're very good.

Easy to use and super strong! no issues with hold and holds decent amount of weigth.

I loved how strong and sturdy these magnets are but when they came they were very very small. It might say the measurements but the picture makes it look much bigger. Also within about a half an hour of opening them, one if the magnets broke. I still think that if you just need small magnets it's a very good buy. I'm still getting them again but I will just get a bigger pack and tape it together.

Magnets are extremely strong and will fit any DIY needs

Does what it says it will do! I used it to close my air filter door. I stacked two together and it did the job!

They are deceptively strong for their size. I needed strong, flat magnets to make a new window covering on our metal door. I sewed in three across the top and they do an excellent job. The fabric is very thick and lined too. When pulling two magnets out they were so strong that they pulled out of my hand and back to the others. That's when a couple broke. Overall, they are great and just what I needed.
