Hi everyone... I noticed that the surface of my YSL card holder in grained leather is starting to feel a bit sticky and I'm not sure why. When comparing the feel with the inner part of the card slot, I can tell that the exterior definitely feels more sticky. I tend to shove the card holder in my (clean) jeans pocket when I go for lunch break at work, so I'm not sure if that could be the cause? Anyone has experienced the same issue, or have any possible solution to remove the stickiness? It's not too bad to the point where dust or lint will stick to it--I'm just bothered by the feel of it and hope it doesn't get worse
