I own an antique 1900s sterling silver overlayed amber pipe, and it has its original leather/hide case.
The tissue paper it was in has absorbed a disturbing amount of oil or grease from the case.
What is it, and how do I care for the case so it stops leaking? What can I condition it with or how do I clean it!
I've never handled this problem before, only antique and vintage crocodile and alligator skinned items.
