HIGHEST FOOD GRADE MATERIALS: 316 SURGICAL STAINLESS STEEL LID - 316 Stainless Steel is used in biomedical applications & has the best rust-proof properties, moisture tolerance, strength & food safety. 100% GENUINE SILICONE - NO FILLERS - NO WHITE WHEN PINCHED: If silicone turns white when pinched or stretched, it indicates low-quality silicone or added plastic fillers. We are paying extra for the best silicone for durability & food safety. 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.
