Thank you for viewing. This is a set of 62 mycelial bottles, 800cc each. They were used for raising beetle larvae. They have been washed, but there are bite marks from the larvae and some remaining soil stains. Please be aware of this if you are considering purchasing. These are being sold at a low price, so they are recommended for raising larvae. A Tyvek filter for mycelial bottles is required for raising them. Please note that no claims or returns are accepted after purchase. They will be shipped in a size 160 cardboard box.
