This Michael Kors wallet is everything I was hoping for and more. The quality is excellent for the price - sturdy stitching, smooth zipper, and the material feels durable but still soft. It’s the perfect size for everyday use: compact enough to fit in smaller bags, but still spacious enough for all my essentials. And can we talk about how adorable it is? It looks way more expensive than it actually is. If you’re on the fence, this is your sign to buy it. I’m seriously considering grabbing another color.

Perfect size for small crossbody

Size: One Size, Color: Brown/Acorn

I bought this for a small crossbody purse. My other wallet took up too much valuable space. This wallet has enough storage for most of my cards, has a change section and seems to be well made.
