That wall is like the dream! I may have to investigate on a large case or maybe do a bit of work with a display to put mine in now I’ve seen this… The wallet keeps on bleeding far past cards with collecting haha.
Can’t you get glass which helps the cards not get so faded? Luckily I live in a cave with eternal darkness so it’s not an issue for a cretin like me. On a serious note I live in the UK where it’s almost never sunny so is it likely to be as much of an issue if at all compared to the states if I have the aforementioned glass/screen?
There is a glass called Museum Glass that is 99% UV protection and has awesome clarity, or there is Conservation Glass that also has 99% UV pertection. both will help with cards not getting faded and protect them.
