This is my favourite - Chloe A/W '02 Tourbe (dark brown) Continental Wallet with amber resin clasp (on left).
I like it so much, I've never used it inside a bag - only as a clutch.
I had to buy the (black) French Wallet variation of it to use inside bags (on right).
I'd happily buy more, if they weren't so rare.
I'm always looking for the clutches from this line, too, but they're like hens teeth, as well.
I think, of the few that were made, most must have been worn-out and/or the people who still own them like them far too much to sell them!
