I have successfully used this bag as my everyday one for a year and a month almost to the day from the purchase before the stitching around one of the zippers came undone, strangely for the second front pocket that I almost never use. For the most part besides the stitching everything else held up amazingly. It doesn't even look worn and generally any stains were easy to fix by wiping with a wet wipe. The material still looks new. The lining is sturdy and did not rip. I am now debating on getting a new purse or just fixing the zipper because I love how much space it had. I had the 11.8 sized one. Here is what I would usually have in it for my everyday use. It would fit my slim reusable waterbottle (or a can of soda, or an Arizona can), fat large men's wallet because those large skinny ones for women that look like clutches are so uncomfortable to me. A pair of extra large sunglasses that go over glasses in their hard case. Over the ear large headphones, I got the foldable ones, they still take up a ton of space but so much comfier then crappy in ear tiny earbuds. A soft clutch with makeup. Those small envelope ones. Powerbank and charging wires. Smartphone. Keys. The big plastic roll of sour raspberry bubblegum. Various snacks. To be honest about a pound of receipts... A small art pad to draw in with a few pens and a few pencils. Small scissors and small long nose pliers. A multitool, and a also a multitool pocket knife. Don't judge. Pliers are useful. Wet wipes for face and hands. Allergy meds, pain meds, bandaids and alcohol wipes in a small soft bag as tiny medkit. Travel chopsticks, fork, spoon and straw. An 2xl reusable grocery bag. 6 cotton handkerchiefs that are around bandana sized so I could use them for my head or for cleaning or wiping. And obviously just in case feminine products, I like to use reusable ones. And that is about it. Honestly it's a stupid amount of stuff but it fits so... And it's very compact sized, not too big and lots of pockets so everything stays organized. It doesn't look like much will fit but I like tetris and you would be surprised. Still think it's strange that the one pocket where the thread around the zipper broke was the one pocket I barely opened ever. What a bummer.
