Yeah definitely too bulky. I have 2 keys and a small R charm in the middle of the two keys, plus some bandaids in the back part and it's a little bulkier than I'd like.
I have eight keys on mine - I have the pomme one - if they are regular sized keys there is no problem. I actually have 7 regular keys on mine and then my big car key - I leave the car key hanging out. I have no problem closing mine as long as the car key is out.
