Unicorn bags for mushroom growing are made of polypropylene so you can fill with substrate then sterilize in an autoclave or pressure canner.  Once cool inoculate with your mushroom culture in your sterile lab or “still air box” and seal.  Bags can be sealed with an impulse heat sealer, bag clamps, or zap strap.  The filter patch allows for air exchange while keeping contaminants out.

Sold by the box of 1,000 or in bundles of 10 or 100 bags.
