These large collection bags are made from 100% sustainable organic cotton, dye/chemical free, vegan leather, and machine washable!     These collection bags are made from durable cotton canvas. The large 7x12x7 interior (588 inches cubed) of the bag offers more than enough collection space for a few pounds of mushrooms. These discrete bags are unwaxed allowing the mushrooms (or plants) to breath and still be able to distribute their spores.     
 
When not in use, the bag can be folded up and carried in your pocket until ready to use.
