Don't get your hopes up about the lambskin. I have a Marc Y Marc Ukita in lambskin and it has worn much faster than any of my other MBMJ bags. Lambskin is just too delicate...or at least the lambskin on that bag is.
That's a shame! I have a Petal to the Metal Natasha in lambskin and it's absolutely divine. It still looks brand new after years but I do know what you mean about the lambskin. I bought (last year I think) the St. James Kitty Messenger bag and within days looked beat up so I sold it on ebay because it was too delicate and soft for me.
