It's great for indoor/outdoor use as long as it's protected from moisture.

The Best Way to Separate Strong Magnets

Instead of trying to pull strong magnets apart, firmly slide and/or twist them away from each other and far enough apart so that they don’t jump back together.

Small strong magnets. My husband bought these for a project he's working on in our garage. He's used them with cabinet doors and misc items.

Not as strong as I hoped for probably due to the hole in them.

These were way better than I was expecting. I've been using this type of magnet for years and these are far and away the best I've ever gotten. Will be getting these again!

Magnets are not 10mm, but rather 9.5mm. A typical countersunk M3 screw does not sit fully flush in these magnets either, rendering them useless for my application.If you want good magnets, amazon is not the place.

The good:- They are pretty strong magnets!The bad:- In the set that was sent to me, ALL of the magnets had the same polarity, so, if you're hoping to use screws to attach them to whatever your project is and expect both pieces to snap in place, they will actually repel, which is the exact opposite of what you'd think they will do... Although, if your project is something that requires repulsion, say, a floating device of sorts, or you want to use them to attract metal, then this is the magnet for you.- One of the magnets arrived broken, and they do seem somewhat fragile.
