Yeah back in 8/2006 i was munchin on a bag of cashews and to my surprise a large piece of glass was in the bag and I was just gettin ready to tip the bag in my mouth. I called Kar's and they wanted me to bring it in and I said no can do. lol I even kept the unfinished bag bag until mice started chewing on it. It appear to be part of a glass o-ring of some sort, so the next time you think about tipping a bag of anything in your mouth think again, because it may be a unwanted surprise waiting for you. peace
