May I ask what location you are at? Was the crafts person on site to do the assessment? I had my box Kelly refreshed a year ago, I am located in NYC so had the benefit of having a flagship store with in house craftsman here to give me a yes/no on repairs immediately. But I had several scratches and some handle discoloration and he fixed it all. It took 4 months but my bag came back pristine like essentially brand new. I wish I had before photos to show you. But attached is my bag post spa!
I would see if you have a flagship store close by where you can bring your bag for a second opinion.
Your bag looks amazing!!! May I ask what the condition was like before? I have a box kelly that has some glazing rubbed off and one corner is kind of chipped, if that makes sense. Wondering if H spa will bring it back to life too?
