Hotel Key-card Collection for 10 years

Among the souvenirs of the trip, hotel card keys are one of the things that you can get very easily. It depends on the country, but in the case of the Americas, Europe, Australia, and New Zealand, they often just give it to you when you check out. Depending on the hotel, you may have to buy it or pay for the loss, but it's not that expensive, so you just have to pay as much as you want. Of course, there are places where they don't give you card keys, and you can't collect regular keys or special-shaped keys, but the card keys alone are enough to make a nice collection.

I have a question. What is the safest way to store plastic hotel key cards?
I used to store them in Ultra Pro plastic sleeves and semi-rigid holders, just like collectors store baseball cards.
However, a few days ago, I was looking at them, and I noticed that mosture appeared on them. Naturally, I removed the cards to prevent damage. Thankfully, none were damaged. Is it possible, that the combination of plastic sleeves AND plastic cards caused mosture buildup? I keep them at room temperature.
Currently, I have them in a box. Is there a safe way to store them long term, without any damage? Any mosture will "wipe away" the ink. I know some collectors use 8 pocket plastic pages. However, they are no good if they're going to cause the ink to run.
Currently, I have over 200 different key cards. Just a small collection. I started collecting them during this pandemic. Since I can't travel, I'm going to bring the world to me.

제가 처음으로 호텔에 묵어보는데 카드키나 어메니티, 볼펜 가져가고 싶으면 프런트에 말하면 되나요?

[@user-bv4ns6rj9q]

리필용 어메니티 발고 일회용은 가져가셔도 될거에요! 볼펜 메모지까지는 오케이고! 카드키는 프런트에 문의하시면 주는데, 이왕이면 기념이라서 가져가고 싶다는 제스쳐를 취하면 선물로 무료로 주는 곳이 많습니다! 카드키 같은 경우 체크아웃을 하는 순간 비활성화되서 다시 사용못하거든요 ㅋㅋ 호텔이용시 가져갈수 있는 아이템들이 궁금하시면 제 채널에도 방문해주세요!
