Mushroom bags (mycobags) with filter patch. Made in China.

Some mushroom cultivators prefer these Chinese bags over our USA-made bags for their extra thick, 3.2 mil plastic. Although thicker than our USA-made bags, the downside of these Chinese bags is that the filters are not composed of the same material as our USA-made bags. The filters on these Chinese bags can be prone to tearing during sterilization. We recommend ordering a small quantity of these bags to test with your application before committing to a larger quantity order.

Alternatively, please see our USA-made bags.
