Apart from the natural process in terms of getting way darker, I have spotted the plastic case underneath the leather. It seems that the leather doesn't coap too well on the edges. I only keep my phone in the pocket, don't throw it around, it didn't fall in the ground or got in contact with sharp objects. The overall quality is okay and I'd maybe buy again a Vaja but only if a search doesn't show another great product with similar quality and a lower price or higher quality at the same price level.
