Review on MIKEDE Strong Neodymium Disc Magnets, 16 Pack Powerful Permanent Rare Earth Magnets With Double-Sided Adhesive, Fridge, DIY, Building, Scientific, Craft, And Office Magnets, 1.26 Inch D X 1/8 Inch H by Stephen Russian

The description of these is accurate; they are very strong but also very fragile. They are NOT children's toys! They work very well for my needs. HOWEVER, read the description and instructions CAREFULLY! Keep away from each other, slide one off the stack as needed rather than trying to pull off the stack, and KEEP AWAY FROM EACH OTHER AND FROM METAL SOURCES until ready to carefully place where needed. They are SO strong, they will fly several inches to each other and metal and will shatter on impact if allowed to do so. I think (?) this is the nature of this type of magnet, and not a flaw in this particular product.
