actually the BV bags can be quite light and IMO they are very good quality - though of course you won't be able to take it back for a spa or repair generally.
AU CONTRAIRE! Bottega Veneta will do any and all repairs - they will rebuild a ripped lining, reweave the exterior of the bag. They will replace or repair handles.
They will not clean. That's the ONLY thing they will not do.
My DM loved BV in the late 70s and 80s. These bags have seen 20-40 decades of hard living - and they have all needed and received repairs at various times in their lives.
