WHY USE 316 SURGICAL STAINLESS STEEL, NOT PLASTIC OR ORIGINAL CANNING LIDS? Even though the lid is on top, liquid vapors collect & drop back down. Canning lids rust, has PVC/vinyl (worst type of plastic) coating and seal. Studies show most "BPA-free" plastic is NOT BPA-free and/or replaced with worse chemicals. Plastic sheds micro-plastics & leaches harmful chemicals, pollutes environment & harms/kills wildlife. 316 SS lids with silicone seal are safest option for health & environment.
