Review of Magcraft NSN0604 1-Inch by 1/8-Inch Rare Earth Disc Magnets, 4-Count

The Magcraft 1" Disc Magnets are very strong and well made. These are very high quality magnets that are perfect for science projects.

These large disk magnets can hold a lot of weight and some care should be taken when you have a bunch of them together as they are very powerful. We have taken the advice of other reviewers and have not made the mistake of letting these smash together, so have not seen the chipping problem some others have reported.

Be sure to save the packaging as it is well made and likely the best way to store these when not in use.

Highly recommended!
