But did you know that many Mason jars come with lids that rust and that have a plastic lining on the interior that often contains bisphenol A (BPA)?
These regular mouth stainless steel lids are a safe, rust-proof, and plastic-free alternative to the ones that come with standard mason jars. They are leak-proof, making them great for packing drinks or food to go.
These lids are also easier to keep track of because they are a single unit, rather than the typical two-pieces of flat lid and metal ring.
Please note that these are not meant for canning or processing purposes.
