If the bag was retouched, and not by Hermès, then you cannot have it treated by Hermès in future. This isn't ideal for a box calf bag as the ability to restore these bags to a high level is one of their best assets. It also lowers the resale value considerably. That said, it looks sprayed, not retouched, which is frankly worse. Personally I would reconsider.
Thanks for your advice ~ ya, I've decided not to take this kelly... I just went to the shop to view it... It is quite hurt the bag...
