The depth is very slim. I was able to fit my long flat card wallet, tissues, lip balm, card pouch and key pouch. As my long flat card wallet was rather long, I did have to push it in further whenever I want to zip the bag close. I will not say that it fits a lot but it does fit the essentials. Due to its slim depth, it does not allow you to stuff more things within, cos it then shows bulges and you will also need to remove things on top to get to the things at the bottom. I like the bag for how compact it is but eventually I did rehome it cos I had to play tetris with it. All said, I still miss it from time to time as it really is a very compact crossbody and if you carry little or intend to use it as a companion bag (with backpack or tote), I do think it is very useful. I have nothing bad to say about it. Just purely user preferences as I prefer to stuff things in and not having to worry about placing them properly before I can zip it close. Hope this is of some help to you. Which colour are you eyeing?@frenziedhandbag , was wondering what you're able to fit inside?
