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.

Amazing!

Color: All Black

Love this bag! It’s just big enough to fit everything I need and elevates my outfit with the leather and metal accents! I’ve had mine for over a year and it still looks brand new!
