Very cute and spacious for something that looks small. Had ample pockets for organizing small things. Large enough to carry my small wallet, cellphone, portable mini fan, hand sanitizer, lipstick, compact powder, eyeglass w/soft case; mini compact with nail clippers n tweezers, dental floss..things you need when going out for the day. Well made and Worth the purchase.

Small.
Color: All Black
Cute an stylish. Great material and looks fashionable. Shoulder strap gives it a nice look. The size is a little small. I usually carry snacks for my kid but this bag is a little small for that. I only fit, a small pack of hand wipes, hand sanitizer, wallet, keys, phone and chap stick. Maybe a small snack but it’s tight. Very cute bag though.
