This trifold bag has three separate compartments one that has a zipper, in the middle there's a strap to keep things in place and then in the third part there's three pockets, two being small like for a credit card and then a bigger one to easily hold paper currency All the included accessories, It makes it easy to carry small particles. As an experiment using some of the small containers, I put freshly ground coffee in one of them, minced onions and minced garlic. The containers themselves do an excellent job hiding the smell, and once I fold up the bag, I cannot smell anything. I've been told by many people that I have a very good sense of smell. So overall I am very happy with these and it performs as advertised.
