Customer Reviews:

  • 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....more info
  • Excellent magnets
    I bought these for holding a magnetic knife rack onto a fridge, but also ordered the 1/2" x 1/16" round types which work better because I need 3/8" to come flush with the housing.

    We have not had any problem with chipping, no signs of fragility, but they are very strong. Our fifteen year old finds them extremely difficult to separate, the adults just find it hard work. With damp hands I can't remove them from the fridge, and even dry I have to rock them to break the hold.

    They come in a double walled tube which is just sufficient to keep them from sticking to everything and messing with any ferrous metalwork they come close to.

    Good to play with, but be careful round credit cards, CRT monitors, and anything else that is susceptible to magnetic fields....more info
  • Unbelievably strong.
    Really ... it's actually difficult to imagine how strong these small magnets are. I am totally amazed.
    Nicely finished product too.

  • Impressively Strong
    Damn they are strong. Kinda fund item to have. Never really understood magnetism, and now that I have these, I still have no clue how magnetism works. But I do have fun playing with these :)...more info
  • super strong
    these are very strong magnets
    they stick together through your palm pretty easily when new and can stick through your wrist
    i recommend you wrap them in some sort of tape because they do slam into each other/other metals and chip
    these are strong and you will have a lot of fun messing around with your friends with them...more info
  • 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....more info
  • 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....more info
