I wish I would have sprayed mine with leather protectant first as others have suggested. Mine does show a black film along the edges that even leather cleaner will not remove. That said, I put the case back on my phone today. It simply is the best best case I have ever put on my phone. Maybe for Christmas I will get another red one again and apply a protectant on that one. Or I will quit being a sally and just enjoy the worn look on this one.
