Amazing
This little magnets are super strong!!! So strong you won’t be able to pull them apart, you’ll need to slide them apart.
The only downside, they are brittle. They look like metal so one could assume they will take some rough treatment but when I screwed them to some wood and overtightened them a little, they fractured.
If you know, it’s OK. You just need to be careful not to overtighten the screw.
