You mentioned they rejected your bag due to "condition". I know you said it's definitely in good condition; however, have you had any work done on it, like dying or painting? I know sometimes they will decline a bag if it's been painted (or dyed) however I've seen bags they listed that have had work done (painted or dyed) as it's in their description. You can try to submit again as I have been rejected due to too much inventory and literally in about 30 days I tried again and they accepted it. Perhaps it depends on who you get as a buyer. If you are local submitting in person is better imo as they can see the bag in person.A few months back I submitted my vintage Chanel black/lambskin classic flap and they rejected the quote saying it was due to "condition." My bag is not pristine but it's definitely good condition
I found this weird because some of the vintage chanel bags they had online at the time were actually in terrible condition. I saw a classic flap that actually looked like someone sat on it.
I ended up emailing them to ask and mentioned the condition of similiar bags on their website and they sent me some BS generic automated response.
