LV will not take a repair/refurbishment job if another leather person has touched the bag. I assume H is the same way. That's the real risk of using an outsider: the manufacturer will never allow themselves to fix it up.
$600 sounds dirt cheap to refurbish any bag these days.
I didn't know that ostrich could stain.
If it were me I'd associate the bag with such bad karma that I'd sell it for, oh, I don't know, $8K maybe, and move on. Was the bag colored silver in the transformation? I like silver and from what I can see it looks nice compared with the stain-prone original.
Check your bag for the parts. I got a
Coach bag restored (re-dyed) and while the color is good, the repair shop replaced the Coach clips with faux ones. I had the bag re-dyed b/c I used and liked it so much. I haven't used it since I noticed the clips were faux replacements, which is to say I haven't used it at all. I could have gone back to the shop but I'd waited a month or two to look closely at it. Plus I figured the owned wouldn't cop to taking the parts and it would just be a nasty experience. One day someone visiting Goodwill may find a Coach Willis bag looking great aside from the clips.
Thanks for passing on what you learned in this awful experience.
