I opened a bag of the snickers, m&ms, starbursts, and twix variety pack this morning. The bag was brand new and I brought them to school to assemble halloween goodie bags for my students. As I was putting them together, one of the m&m bags was empty and torn from corner as if someone had opened them and thrown the wrapper into the bag.. There were not spilled m&ms in the bottom of the bag, just the empty, torn wrapper. I took photos and can send them. I am just wondering about the quality control on these products. I have always bought from Mars before and was disheartened and concerned to see, what seemed to be, an eaten and discarded wrapper in with the other unopened candies. I can attach the photos in a future email, I look forward to your quick response.
