Beautiful pictures. I use the men's large leather travel case as a travel make-up case. I have it in brown leather. It was a gift to my DH and he isn't into Hermes.
I've already got a silver chain keyring (looks like a clothes pin and works, too) as well as a few of the fruit ones, but I'm wild about that stirrup. Gonna talk myself out of it though.
I have this one (circled below) and it's fantastic. It's a valet clip which separates in the centre. Fits the giant keys that come with most cars these days too.
PooLoop... Sorry for the temporaily lapse in dirty mind land.
It looks much more useful for valet car keys, one of the nicer function keychains that H makes. I'm assuming the leather part is detachable, like the LV one.
