Review of Magcraft NSN0577 1/8-Inch by 3/8-Inch Rare Earth Rod Magnets, 40-Count

From personal experience, I associate Rare Earth Magnets with pinching and the snapping sound as they adhere themselves to my fire door, relatively permanently.

These are strong enough to use practically like pushpins on a refrigerator, but will not pinch your fingers.

Also, they are super fun to build tiny structures with.

Enjoy.

Review of Magcraft NSN0732 3/8-Inch by 1/16-Inch Rare Earth Disc Magnets, 40-Count

Neodymium-Iron-Boron rare earth magnet: 3/8" wafers... The north and south poles are through an axis of the "cylinder", as you would expect. This means they want to form a long "rod". It is almost impossible to push them north to north, or south to south pole (probably 10-15 lbs of force). When you play with them like this, they actually start to get hot from the magnetic "friction. You can make one of them "dance" and stand on edge at about 6" away. Don't throw them, or let them "snap" back into the stack, these wafers are very brittle (I've already cracked one). They seem to be chrystaline or cast metal, but chromed.

Review of Magcraft NSN0579 1/4-Inch by 1/8-Inch Rare Earth Disc Magnets, 40-Count

These are very powerful little magnets.They are not for small children.They are great for organizing the kid's artwork and such on your fridge.Just a couple of them are enough to hold our large calender to the fridge. When transporting my kitchen knife to a picnic or BBQ, I make a sheath by rolling up the knife in several layers of paper from a brown paper bag and then use a couple of these magnets to secure it.The paper doesn't unroll or slip off the knife.I put one magnet in the tip of the driver bit for my drill/driver, now I can dip the tip into a box of screws and pull out six or seven at a time.I bought some larger magnets also, they are insanely powerful!I use one to help keep my screw and nail containers organized.No more poked fingers trying to get sheetrock screws out from the bottom of my bag.A fun and useful product.
