This cute and functional bag was bought in NY in 2005. Since then, I've used it to hold my jewelry when traveling. It is made of black nylon with a zip closure. The Prada steel logo completes the look. I have the card of authenticity but not the dust bag. This little bag is very clean. It's approximately 6 inches by 3 inches. You can't put a cell phone in it, but you can put lipstick, makeup, etc.
