DIYMAG 4 Pack Strong Neodymium Bar Magnets，Powerful Rare Earth Magnets Heavy Duty Metal Neodymium Magnet with Double-Sided Adhesive for Fridge Kitchen DIY Craft and Office Science, 40x10x5mm

These things are amazingly strong. I have at least one pinched finger by not respecting their power!One thing to note is that the North/South are on the large faces of the magnet. I was actually looking for a traditional bar magnetic with the N/S on the ends but these will still be useful for other projects I'm working on.

I got these to use in my motorhome. I had a furnace cover that was screwed in I wanted easier access to. I put some magnets on the cabinet frame and cover. Screws held things in place well. I have about 500 miles or so on it, and they have stayed in place great. The door never moved when I wanted to to stay closed, but was easy to open when needed.

Es ponte

Exactly as described. I am looking to use to secure objects to the side of my aquarium and was able to make a pretty good bond through the glass. I have a larger/thicker tank so I would use two pairs to get a better bond, with that I wish I had ordered the 40x10x5 magnets to get better holding power. These are strong magnets and will be useful for various projects.

Love these magnets great power to them and they stick very well i would get more of this when i need them

Amazing, strongly recommend it

These are nice but nowhere in its documentation does it mention the "N value" (N-Value refers to magnet strength) they are not real strong.

Great purchase and fantastic to buy from!!
