I have the mini pochette, and LVoe it. It's always attached to the D ring in my Speedy, sometimes I take it as a wristlet when I go to the store.
It holds my keys (car key+house key, bulky) plus card holder, with all my debit cards, store cards, sometimes I throw in some change, receipts etc. I don't put makeup in it, cause all my lipglosses tend to leak, and I don't want the inside of the pochette to get smeared.
I seriously love this little bag, love the chain, and the fact I can always easily reach into the Speedy for my keys and cards, but if you want something to hold your iPhone, cigarettes, cards, lipgloss and keys, maybe you'll be happier with a regular size pochette. Or Mila, I think that one is lovely.
