When buying a stash box for your cannabis goods, you may want to consider the following features: material, odor control, portability, compartments, closure, and cleaning. Size matters, especially if you’re someone who likes to roll on the go. Rolling trays come in different shapes and sizes. If you like to carry your stash and supplies and already know the size of your ideal rolling tray, you can search for a stash box shaped to fit your favorite rolling surface.
