The very same bags that I use for experiments, I find it’s convenient to cut them down into smaller bags & resealing. Originally intended for spawn use, I have had nothing but great experiences when using these for spawn, substrates or simply as a flexible vessel for sterilizing tools.

These bags are no longer manufactured due to the high costs of creating a full length, waterproof filter patch, and I have around 20,000 of them on hand. They were being sold for $1/ea by the case of 1000, individually I am offering them at $1, but in bulk quantities I am happy to offer them for almost half the original price.

If interested in full case of 1000 bags, email and I’ll send you a shipping quote.

I have reused them in the past, they work well for sterilizing spawn & make excellent bags for fruiting substrates, right from the bag.

Any questions? Reach out!

Dimensions are 26.5″ X 12″ – pictured in the gallery is an example of the bags cut up into 1/4’s & used for spawn & the grey oyster photo pictured was also fruited from 1lb substrates cut from these same bags again in 1/4’s. These bags are a great value and they don’t make them anymore, so you’re getting the last of them!
