      Disappointed

      I ordered Natto spores 2 times before this order. Both time, I got a tiny bottle of Natto spores and I was happy with it. You could make more than 60 pounds of Natto if you used this 3g of Natto spores. Now, this order, what I got was deluted Natto spores which only can make 8 cups of Natto. Price was exactly the same. I feel ripped off!

      spores not working

      We are not finding your spores effective. The spores we got from Japan made the best Natto ever but after four batches with yours we are not getting any fermentation.
