10 Mushroom Spawn Bags With Injection Port ( small size - empty)

Ten empty mushroom spawn bags. Made in the USA by unicornbags.com

The bags you will receive are the same ones we use to make our pre-sterilized grain and all-in-one bags. They measure  4″ X 3″ X 18″, they are the perfect size for 2 quarts or about 2 pounds of hydrated grain.

They feature a pre-installed injection port as seen in the photo, and a .2micron filter patch
