Zen roll boxes are quality machines that can make all the difference in your cigarettes. They make it easy and affordable to roll your own smokes, and these machines are built to last. The Zen 79mm roll box was specially designed to operate smooth and create the perfectly pressed cigarette, every time. The hinges are lubricated to provide long term use with no binding or sticking. Made of thick steel with a pristine polished chrome coating, these roll boxes look as good as they roll.
