This is a thirty one black and gray bag. Great for a traveling bag, toiletries, makeup, etc. There's 3 removable clear bags 1 large and 2 small. There's a velcro strip on the inside of each section that they attach to. its that easy. see last 2 photo's...couple of blue marks. looks like ink but not exactly sure. and 3 small dark grey marks on back of the bag.
