Hey there! My card holder that I left in my pants like a complete moron kind of warped, pretty much how yours looks like on the edges but the lining got ruined. Don’t do anything to it like leaving it out in the sun but definitely add some leather conditioner so the leather doesn’t dry out and those little moisture absorbing packets did help. Hopefully you let it air dry cause I think the leather cracked for others who ran into this issue. I used it for a while after that and as much as I hate resellers, I sold it on
Fashionphile and they bought it for $250 because it didn’t really make me happy anymore. Luckily a pop up store arrived near my area and the store was STOCKED. I was able to get a replacement flap card holder in beige and I’m loving it
