Inquiry (采购产品): 3lb tins and lids I own the Super Suppers in Boise Idaho, and we purchase our tins and cardboard lids from you. Last week I called and asked if the cardboard lids were oven safe, the answer I got was "we don't know no one's ever asked". I need a more definate answer than "I don't know" are they safe to leave on when cooking? to what temperature? etc...Please get back to me on this matter.
