Set of 4 replacement magnets for our magnetic keyguard attachment.  Measure the magnet pocket on the keyguard to see if you need the 1/2" or the 5/8" magnets.  The top magnets the fit the pockets are 1/8" thick, and the bottom magnets that attach to the case are 1/16" thick.  1/16" bottom magnets come with VHB adhesive dots.
