Cute mini backpack
I love the color, pockets are deep and zippers are smooth, it’s plenty deep and wide just wish it came in a 13/15 inch so it fits my planner but it works with a 5x7 one just next time I know if I want to fit a notebook in to get a bigger one

Love this bag but the straps always adjust and loosen
I love this mini backpack purse. It’s soft and lightweight and it’s cuter than I thought it would be. The extra pockets help keep things organized and I like to keep my debit cards in the back pocket so I don’t have to open the whole bag and dig around for my card. The only thing I don’t like is the straps slide and adjusts especially if I grab it by the strap so I always have to slide the buckle back up to shorten the strap. I’ve thought about putting a small zip tie or something to tighten the strap and hopefully it would stay in place.
