This is a popular CHUMS pouch/sacoche. The transparent back makes it easy to see your airplane tickets and other items. It's convenient for carrying the bare essentials like your phone and wallet when you go out, or for keeping valuables close at hand when you put your bag in the overhead compartment on a plane. I've used it a few times, but there are no stains or tears, and it's still in great condition. Size: Approximately 13cm (height) x 21cm (width) x 2.5cm (depth). Thank you. Color: Black Stains/Tears: None
