This lighter is more than just a lighter; it's a historical memento. The inscription "1973 FIRST PACKAGE IN JAPAN" on the edge and "50 YEARS IN JAPAN 138/150" on the back indicate that this is a limited edition (only 150 pieces worldwide) specially released to commemorate the 50th anniversary of Marlboro cigarettes' first sale in Japan in 1973. Marlboro holds an extremely high cultural status in the Japanese market. Such commemorative editions, with their specific historical year and extremely limited quantity, are highly sought-after and rare items on the collector's market.
