Neodymium Disc Magnet Ø20mm

Strong! Definitely impressed.

I needed stronger magnets than the cheap ones I usually get, so I decided to give Magfine a try. I'm impressed. These 20x5mm magnets are crazy strong. I don't understand the technicals around magnets, but if I put two of these directly together (they ship with plastic spacers) I'd be worried I wouldn't get them apart again. Again, truly impressed and I'll be back when I need more.
