This is a six-key case from China Northwest Airlines. It can also store coins. Design: Coin case, 6-key case Color: Blue Size: Length: 7cm Width: 10cm Thickness: 2.5cm Please note that there may be slight variations. I found this while cleaning up my parents' house. It's unused, but it was stored out of the bag, so I'll classify it as "Like New." I don't think there are any noticeable stains or scratches. China Northwest Airlines merged with China Eastern Airlines in 2002 and no longer exists, so this is likely a rare item.
