ENCASED NEODYMIUM MAGNET PKG(2)
Beats us, frankly, but this black plastic cover, 1-3/4” x 1-1/2” x 1/4” (not unlike a tiny toilet seat cover) is hiding a really nice 1” dia x 1/8” (think: quarter size) plated neodymium magnet, with at least a 8-lb pull, inside. The mystery is that the cover won’t open unless you break it. The magnet grabs fine in the case or out of it. Tap it on its side with a hammer to crack open the case and reveal nothing but magnet.
