I’m using iPhone 13 Pro and it fit fines, after putting the phone in I don’t think it can accommodate another pouch however slim without stretching the leather flap which in long time may not be good, unless you don’t mind it, after fitting my phone in it can fit my Chanel card holder and put my lip balm on top of the phone, if you put the air pods in it would not close lol hope this helpsOne question please: Does the Constance on the go fit a iphone 11 included a lv 6 key holder? Thx for advance
