So I am trying to decide between a Mono Clefs or Mini Pochette. Looking for something for my car key and credit cards I can just grab out of my bag, Neverfull MM, if I need to run in to a store quickly. I would also want it to fit in my Pochette. I think the Clefs would be fine but the Mini Pochette is so darn cute. If you have both or have chosen one over the other why?? Thanks in advance for your help.
