Chicken with edamame 400g

맛도 좋고 아주 맛있습니다. 재구매 예정입니다.

Can someone explain to me what exactly is going with this dish? The broken plastic (black) was inside the food when I tried to check after seeing the black lunch box got cracked. Last month, I had one dish item that also got cracked from the cover and some crystal broken plastic was inside the food. I don't know if it's the packing problem or the delivery problem. I already sent a message last month that said someone needs to be careful with either the packing or the delivery but it's still happening again and a lot of them this time..
