This is a very nice well made bag with a plastic cup in the bottom so you can stand your tank on end as well as rubber feet on the side so you can lay it down. It also has two detachable pouches on the side. I only took it out of the box to see if it would fit my 9L tank. It says it will fit a 9L tank but it doesn’t. That’s the only reason I’m selling it. $130 shipped.
