not trying to diss at all, but if they have sat in storage for years and have those kinds of creases, then the leather most likely has gotten very dry and therefore the creases might be very permanent.
i am not saying that they cannot be made to look good again, but my guess would be that they need someone to professionally steam them, properly restretch the leather to remove the creases and then apply many coats of a leather conditioner.
Good luck with the sale, and if you reduce the price, please pm me first.
Thanks in advance.
