Why in the world would Amazon want to sell an item and say can be ingested,  when it clearly has ingredients that can cause cancer. Wish every state would wake up like California and ban all these cancer causing things.

I thought I was purchasing a high quality item but it's not all that. The chocolate is very sweet and as you chew on this product you can tell the chocolate is loaded with sugar by the crunchy texture. I'm going to say it's not worth the money and I'm not satisfied. At the same time of purchasing this product I also bought Sunmaid chocolate covered raisons which I rate from a 1-10...a 10. Now we are talking about yumminess!!!!! So customers...if you are going to choose...let it be the Sunmaid...you won't be dissappointed

in my opinion these are heads and twos above any pickle that you normally find at your local grocery store.  a lot of nice, sweet, pickle flavor.  I probably won't buy again off of amazon because of shipping charges, but if i ever see them locally, i'll buy a bunch.
