10.8 mm x 6.3 mm x 4.4 mm C8 ferrite block

+/-0.2mm manufacturers tolerance on any dimension Magnetised through the thickness so that one 10.8mm x 6.3mm face is north and the other is south. North pole is painted red These magnets are all new, directly from the manufacturer, however, they have been cut from larger blocks and it is not unusual for the edges to have chips and nibbles or for there to be patches of discolouration. This does not affect the either the power or performance of the magnets.
