12 Pack Strong Neodymium Magnets, 40x10x3mm Rare Earth Bar Magnet

I buy a lot of magnets. My wife says I even overdo it too many magnets. What I can say about these is for the money. They are very strong. Not strong enough to go through fabrics but it fully exposed they can hold a lot of weight. If you use 3M adhesive strips, you can lay multiplet side-by-side for a no mess solution, they can hold a ton of weight

These magnets are amazing. So strong.

Wow, these little bar magnets are REALLY STRONG for their size! Watch out for your fingers when you take them out of their small plastic storage case and separate them. And good luck getting them apart if you accidentally get them too close to each other. I super glued three to the back of a white board and the board now sticks to the metal door perfectly; it slipped a little with just two magnets.

These are incredible magnets. I put one on the bench and accidentally brought 10 of the magnets near it. The one magnet leapt through the air and shattered. Take care, especially around children, you will pinch your fingers!

Arrived in a timely manor. They are very strong. Easy to use. Adhesive on back is very strong. Easy to remove. Very light.

Super strong

The magnets are decent but the double-sided adhesive doesn't hold well at all. A set of calipers was enough to have it sagging off and pealing away after only a day.

Definitely strong magnets. I have a new engine that I'm going thru the break-in process with. Being my first new engine, I want to give it the proper break-in & keep the oil clean of contaminants. Especially, as many of the new engine parts that normally wear are metal. So, I'm putting a few of these magnets together in a spot on the oil filter. Hopefully the oil filter in conjunction with the magnets will trap the metal materials in the oil & keep them from passing back into the engine. These magnets are strong & should help.

Powerful as heck! I put one on the bottom of the had and one on top of my hand and they still stuck to my hand from the magnetism. You need strong magnets, buy these. I used them for my fridge to ensure the doors stayed closed. Works great.

so strong i have to slide them to the side of my fridge to get them to come off! exactly what i wanted. i need a bigger package of these

Strong magnets
