LMB is very good.
I've seen the LC Saphir used on a variety of their bags and it works great. I also know that a lot of the old skool french posters on the Hermes forum prefer Saphir for their boxcalf kellys.
Agree with LMB. It had been splendid thus far but always good to have an alternative, just in case. I just read some ladies use Saphir on LV products too.
