These magnets are amazing. So strong.

### ⭐⭐⭐⭐⭐ Small but strong!
*by B***R on July 23, 2026*

Wow, these little bar magnets are REALLY STRONG for their size! Watch out for your fingers when you take them out of their small plastic storage case and separate them. And good luck getting them apart if you accidentally get them too close to each other. I super glued three to the back of a white board and the board now sticks to the metal door perfectly; it slipped a little with just two magnets.
