[交流] 【Discussion】anyone could tell me the reasons

Yesterday I found some cards  have changed colour. They become yellowish, lost luster. It looks bad
I put  these cards in the drawer.  
Is this an inevitable process or does properly maintaining cards prevent from happening?


卡颜色变得暗黄,不知道什么原因,是放在抽屉里的,大概集了8年,一般寒暑假都有拿出来,
这种颜色变化是不是必然的?有没有什么方法可以保持好。


这里看看 这些颜色,多数是正面颜色变化不大,反面很糟糕,






this card white turn to yellow.


以前都没发现 ,看到后很难过,没有好好保护变成这样了。




anyone could tell me the reasons ? Thank you.
