5.0 out of 5 stars Small but strong, March 28, 2007

By	Mike Anderson (Tacoma, WA) - See all my reviews (REAL NAME)

These magnets are small, but they're very strong. I bought them because of a dumb little project I saw online: Add a few of these quarter-inch diameter magnets into the barrel of a bic pen and you can stick the pen right to your refrigerator. Our grocery list has never been so up-to-date!

4.0 out of 5 stars Good product, understandable problem, July 8, 2007

By	Kevin (Virginia, USA) - See all my reviews

This product fulfills its claim of being very strong magnets. They are incredibly strong for such small magnets. The magnets are also very reasonably priced for the large number contained in the package. The one problem is that the magnets chip when they cling together or cling to a hard metal surface. This chipping does not occur all the time, however in the first hour of use, three magnets were chipped. This is understandable because the package clearly states that the magnets are not toys, however it would be nice if the magnets were a bit sturdier. If you intend to use these magnets for more serious matters, then I'm sure they will work perfectly. If you intend to use them for entertainment they will likely be short lived fun.

5.0 out of 5 stars Too useful, November 26, 2007

By	Erin McPherson - See all my reviews (REAL NAME)

My magnets just arrived a few days ago and yet I'm already considering ordering more. Now that I have them here and have seen how strong they are (two of them can hold a calendar up on my fridge which in November is really saying something) I keep thinking of new uses. I'm taking 2 to work tomorrow, no more nametag pin holes in my clothes! Although I initially wanted only a dozen of these for an art project, I'm now planning on ordering more, they're almost too useful!
