Here is a National Flag Badge. The exact official status of these is yet unknown but they may simply be used as a show of support or national identity as other nations do or they may be related to the "Kim" Badges.
This first example is a waving flag made of enamelled copper-nickel with a stick-pin.
Here is another enamelled Badge. This one far more angular and seems to have had a rough life. It is currently quite dark, It'll probably get a wash later.
This rectangular Badge is made from aluminium and has the instantly recognisable DPRK style clasps holding the pin on the back. The production of this Badge is quite sloppy and to the eye it doesn't look as though the star was ever coloured.
