Proenza Schouler PS1 Keepall Brown Leather Large Handbag Made in Italy

The bag itself is not old, not much worn out, the corners of the bottom are not scratched, but it is filled with some kind of liquid. I don't know the composition of the liquid, but the bag is stained. If you have a good restorer or a good dry cleaner, then you will put this bag in order and carry it for another 100 years.
