Ltd 50 Magnets 4x2 mm N52 Grade Neodymium Discs Small Round Magnet 4mm diameter x 2mm

These came pretty quickly, the size was perfect and these are pretty strong for the size.

I contacted them, about how they prevent coronavirus germs from contaminating the package, and I can tell they are professional and their magnets are authentic, I was buying them to customise a speed cube, and fake magnets are a common thing, these are a strong grade magnet and I can tell, they work well with my cube and I am really happy. I would recommend you buy them directly from their shop though, I made the mistake of buying them from Amazon but from their website, they're about 50p cheaper.

Strong magnets.

These did not disappoint, super strong for such small magnets, worked perfectly for intended use. Highly recommended; I’ll definitely be purchasing again.

perfect size for what I needed and good to see magnets with a decent enough strength. I'd be buying more if they weren't out of stock

Exactly as advertised. Would buy again. Used to make a magnetic Rubik's cube. (not Rubik's brand)

These are to hold a model railway wagon's roof in place, while ensuring that it can easily be removed and replaced. Looks promising.
