OMG... too much patina is... AWFUL!!!! Look at this...

I think they must have rubbed leather cream or oil in it. I have had bags for years (and bags that are much older than Gallerias), and they aren't that dark...
 
Is having a patina undesirable??

Depends on the person, and the level of patina. Some people like the patina because it gives the bag character, while some others do not like it because of OCD and the overall look :smile:

However, a patina like the ebay posting is uneven and way dark, which is undesirable. An even, lighter patina is more desirable.
