i have both. it depends on what you want to use it for.
1st one (pochette cles/key & change holder):
bigger (the measurements are NOT the same actually, eluxury screwed those up); holds A LOT more (can hold an ipod Nano even); has two compartments; chain is a bit longer; can be used as a wallet (that's what i do). bills fold in nicely.
2nd one (cles): smaller, easier to fit into pocket but doesn't fit as much. probably only holds 3 CC's comfortably (IMO). i don't like putting bills in there because they get caught in the zipper very easily.
that being said, i get *a lot* more use out of the 1st one. i basically use it as a wallet (pretty much fits the same as the ludlow, IMO). the 2nd one is good for more as a bag charm or when you just want to take keys + a few ccs.
gimme a sec, actually i think i have pics of both side by side somewhere...
thnks girls the cles sounds good. actually i have a monogram wallet porte tresor international. it was a gift from my sister couple of years back and holds so well. i am buying this because am in love with the colour it looks yummy and it would hod coins and my house key too. just confused so thought id ask...
