Master Magnetics 2 Count Ceramic Block Magnets, 3/8 by 7/8 by 1-7/8"

I work at an elementary school and use this on my door frame to hold the door open. It allows me to keep the door locked, but the students are still able to come in and out and it can be easily removed and the door instantly locked when needed. It's small but has a VERY strong hold on the metal door frame, there is zero risk of it falling off at all. I love that it came in a two pack as well so I have a back up a well just in case.

Bought these to re-energize Alnico magnets in a guitar pickup. YouTube video shows how. It works. These are powerful . Don't let them snap together with a finger in between. Ask me how I know.

I have extreme pain & actually have used these for pain relief for the past 20 years for a medical condition. My brother has had MS & was actually given magnets the first day from his MS doctor. They work by placing magnets on pain area & relieves pain almost immediately.

strong magnets. Great for science lessons and science based object lessons.

Strong magnets. Just as you’d expect.

I picked up these Master Magnetics ceramic block magnets to keep my phone holder from sliding down the golf cart frame, and they did the trick...sort of. They match the cart’s color so well that I kept forgetting them and had to go back to find them more than once. They’re probably great for other uses, but for this particular fix, they were just okay. They hold fine, just easy to lose in the shuffle.

Good magnets

Pretty strong magnet that is reasonably tough. I needed something as strong as one of the rare earth magnets but didn’t shatter in a million pieces when you look at them funny. This works great and stands up to literal pressure (from an arbor press).

Awesome, used 2 of these to replace a cabinet door latch. Works much better than the original latch.
