Review on MIKEDE 8-Pack Powerful Neodymium Magnets With Double-Sided Adhesive - Ideal For Fridge, Crafts, DIY, Science, Building & Office Projects - Rare Earth Magnets For Strong Grip by Mark Hayes

These little magnets are brutally strong for their quarter-like size. Not intended to be a toy, these powerful little magnets can easily pinch small (or adult) fingers very easily when initially slid out of their protective sleeve. A word to the wise- make sure to also slide the magnet back slowly and gingerly as they tend to jump quickly to the remaining magnets, and that is where the pinching comes in. So take the time to learn how to handle, then applications are endless! I use the 3M double stick tape that is supplied and have mounted small metal tools to cupboard doors as a space saver, used to secure curtains, prevent chain locks from marring your door due to high winds, keep small metal tools connected and accessible, etc. So be creative, be ingenious and be careful!
