I was a flight attendant before and I had this problem. I just kept losing them. Then I came up with an idea–An empty cigarette pack. Just put the sim cards inside the plastic that covers the pack and its tight enough to hold it. But then I saw a good thing that really helped me a lot. Its a sim card holder that can hold up to 4 sim cards, Its exactly the size of a credit card and so thin so you can put it in your wallet for easy access. Here is a photo:
I got it for like 3 or 4 dollars.
Regarding the labels, you can buy small stickers and put them there. You have plenty of space in the holder to stick labels and write some info for each sim card.
