You have to go yo your H & ask... The bigger issue is because this is
a vintage rouge box the color will not match exactly but it will be as close
as it can possibly be.
Be prepared, you may have to leave the bag there for a period of time
for the whole process to be completed.
I remember several years ago, I was traveling with an exotic vintage kelly bag
& the handle fell off. When I returned home, I brought it to my H store, Claude
was most gracious ordered the skin & made a new handle for me which he also told
me is the most difficult part of the bag to make...
