Very strong little magnets. I used them to hold up a metal sign and it's almost impossible to pull off. Down side, these magnets are very brittle. I drop them on the carpet and they slammed together and shattered.

Excellent product. Very strong magnets as described. I used them to put one in my cell phone case (iPhone 6 plus with an Otterbox case) and put one on the cellphone holder in my truck. Now the phone stays on the holder with just the magnets and it is easy to remove and replace. The magnet is strong enough that it will hold my phone on a vertical metal surface.

Love to play with these magnets I use them for finger exersices to try and take them apart. They are that stong. Just use your fingers and you will see. I got some iron to mess around with these too allot of fun. I use the so many projects. You would be very suprised when you need a super strong magnet as a tool comes in handy for so much. And I alway's these they may cost more but are worth it because of the type they are.
