Has anyone experienced that the leather on their Treesje bags seems to either chip or get kind of wrinkly? I have conditioned my both my Metro clutches and my Pumpkin Asher. I used Wilson's on them. On the Metro clutches they are dry and seem like the leather is starting to crack. Is there anything else I should use to better condition them? Is it worth send them to Treesje to get the leather re-conditioned? Any suggestions would be a great help.
