Rare Earth Magnets</SPAN>
Don't be fooled by the size of these small magnets. Rare earth magnets are recognized for their superior magnetic force and these magnets are true to their name. While these magnets are great for any project which will be hung on a metal surface, they also work well in small box tops, cabinet doors, or other applications where normal magnetic lid or door closing hardware is aesthetically unappealing.
