This is a deck of playing cards from NORTHWEST (Northwest Orient) for use on their planes. It's a Showa-era retro item. I collected playing cards as a hobby, and I received these when I was on a flight. I've kept them stored at home ever since. Only the white box is unused. It's still in its original plastic wrapping. One of the boxes has ballpoint pen graffiti on it. The red box contains conversation cards. I haven't confirmed the number of cards in the used decks. Please refrain from purchasing if you are concerned about the item's condition due to long-term home storage. Available for immediate purchase. Please leave a comment if you have any questions.
