Keeping brass clean, bright and shiny is a real pain. I say this as an ex-serviceman. The merest touch, by hand, can ruin the whole effect within an hour. The actual process of cleaning is also a messy business. We only need to look at the brass name-plates at an office building. The surrounding brick, stone or woodwork is usually stained by the 'Brasso' or other polishing liquid. Once any polishing liquid gets on leather or fur it is there for ever.

So, my advice is this. Why not have two bags? One plain leather and one fur, but have them easily removable for cleaning. You then have the best of both worlds and the bonus of no mess.
