N Korea is increasing its foreign currency reserves with exports of wigs to China.
North Korea exports many kinds of hair products to waiting customers in China.
North Koreans import human hair and other materials from China, and attach the hair to wigs by hand. Profit margins are estimated to be about 5 to 10 percent of export values.
Wig making creates much-needed jobs in the very poor country and manual production is also unaffected by the chronic power shortages in North Korea that cause power cuts.
