I was just at FSH and I showed the craftsman there the scratches on my box Kelly wallet (I threw my wallet into my bag, not realizing I had KEYS in there). He recommended a leather cream for delicate leather from the John Lobb store just next to his counter... I got a tub of that and will be attempting a rescue of my wallet... So this time round I copped out (don't hit me, box fans!) and got a Togo Birkin instead (but my SA told me to continue working up courage cos, in his words, "box is the best leather")... Maybe next time!
