I received this from a friend who was cleaning out their room. They said they hardly used it, but it had been stored in a closet, so there was a slight amount of mold inside the wallet. I wiped it with alcohol, but some traces of the mold remain. It might become clean depending on how it's cared for. The instruction manual also has stains. There's no problem at all with using it. I feel like it might become cleaner with use. It feels nice to the touch and I think it's very easy to use. Currently, I'm placing it in a well-ventilated spot with dappled sunlight to purify it.
