I like this bag a lot. Seems pretty smell proof although I have no experimental evidence haha. It can hold about two grinders, a small pop top jar, a couple of spoon pipes, and any rolling accessories you might need. I even was able to fit my 8 inch water pipe in there just for fun. My only qualm is the main mesh pocket is kind of loose, and when you open the bag and the lid lays flat, sometimes items will fall out. I kind of wish that pocket zipped. Other than that it's great.
Very good size similar to a lunchbox with plenty of room for a good setup
