Customer Reviews

Best magnets for fooling around with
VERY strong. The size combined with the strength of them make them very hard to take apart. You can use the edge of a table to help separate them.

Magnets are brittle. Allowing them to slam together WILL result in them chipping. They are also almost too strong to have them NOT slam together... They are strong enough to pinch fingers pretty good too. Not a toy (for little kids, anyway...).

Packaging is pretty neat as well. Fun magnets.

Very Strong Magnets, Very Brittle Exterior
These magnets are incredibly strong. I've placed all four of them in a row & used them as a stud finder -- they are drawn to nails in drywall like fleas to a dog.

If you allow these magnets to slam together, you may end up with surface cracks and/or chips on some of them.

Very strong magnets
These magnets are as amazing as everyone says. It is extremely difficult to separate two of them. Not everyone can do it. They're great for fascinating the kids. I've have them for at least a couple weeks, and my 10-year-old son was playing with them yesterday. He had one under our two-inch thick wood table and one on top, and he was moving the one on top around (really). They're great for holding thick objects on the fridge, and they're not as hard to pull of the fridge as they are to separate from each other. The force will amaze you, and we have had blood blisters from a person getting them too close and having them snap together. Mine have been played with extensively, and there's only a couple chips, so they're not that brittle.
