Review: Keychain magnets - Got these for hubbies stocking. He dabbles in silver and gold. These are small for pockets. Keeps one on his keys. Has one in his truck . Easy to use. Small but strong. Good for small jewelry pieces. Good magnet strength.
Review: Very strong for its size. - These magnets are very strong. I used them for checking items that I am trying to resell. They get the job done; however, they sure make a mess of my keychain. Every time I pull my keys out I have to separate them from the magnet. I guess it's a little too zealous and wants to attach itself to everything.
