Showa Retro Japan Airlines Cup Set of 12

This is from when my father flew Japan Airlines on a business trip abroad. I believe it's a non-sale item, possibly a boarding commemorative gift.
Diameter: Approx. 6 cm
Height: Approx. 2 cm
Material: Plastic

It was displayed on a shelf and has not been used.
There are some minor scratches and fading of the logo print.
We appreciate your understanding of long-term home storage.
