The only drawback is that they did leave black residue on my fingers as i worked with them so if that’s a concern maybe look elsewhere

Vety strong just careful it can scratch stainless steel type of fridges so just make sure to put over photos and such not directly onto the fridge and youll be fine

You can have a really strong magnet and excellent ironbased surface but a tiny magnet doesnt have the surface area to hold a heavy object

They have a powdery covering in them probably from when they were made they just need to be wiped off

I dropped one on tile and it made a spark before shattering so if youre paranoid youre probably better off getting a different type of magnet

Just didn’t like the grey powdery residue on it

Wipe them off before you use them as they are very dirty
