Perfect compact wallet
Size: One Size, Color: Black
I bought my wife a small Michael Kors purse that needed a small wallet. This matched perfectly and was just the right size to fit in the purse. My wife was very happy. Not a bad price either. Very compact.

“Gorgeous Color and Great Fit”
Size: 9, Color: Atlantic Blue
I absolutely love these Sam Edelman Bay sandals in Atlantic-/Tide-blue. The 9 M fit me perfectly — true to size and very comfortable right out of the box. The leather is soft but sturdy, and the slide design makes it super easy to throw on for errands, brunch, or just relaxing around town. The footbed has enough cushioning that my feet don’t feel tired after a few hours. Overall, great quality and style, and they look more expensive than they really are.
