Hi everyone, this is my first post here. Half of my saturn games just like many saturn PAL games come in plastic boxes with a card cover glued to it. With the time, the card becomes irregular, specially on the back. I'm afraid this is because my house suffers from humidity during the cold seasons but I don't really know if that's the problem. I don't know what to do to prevent this. Most of my card boxes become irregular. Is re-sealing the games a good solution? I usually only use some celophane sleeves to protect all my game boxes. I recently put some silica gel packets around the games and I'm expecting to see how effective that is. ANY tip on how to prevent this is helpful, as I own some rarities I would like to kee in the best condition possible. Thanks.
