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.
