The magnets are great - I didn't want them super strong because they will be used for projects with children. They are strong enough, though, to do what I need to do and they stick together quite firmly.Also, Carolina Biological Supply customer service was fantastic. My package arrived mangled by the delivery service. It had been ripped open and re-taped, but not before the magnets had fallen out, so I received an empty box. I emailed them and explained the problem. I received a kind reply from Duwana, apologizing (even though it wasn't their fault). She expedited a new set and I received it the next day! I was very pleased and would be happy to buy from them again.

Was looking for some simple magnets with a decent amount of power and these did the job. They are nothing 'pretty', but at least act like real magnets rather than some fancy, colorful things one would find at the local office goods store. Yes, I'd recommend these magnets.

Hi, Very strong ring magnets. Perfect size and strength. They give this amount and the magnets are just what I was looking for! Great company and fast service.

Just what I was looking for. Better quality than I had found in the past. Will order again when I need more magnets.

We use these for science projects with our young boys. They are of good quality and have many uses.
