Mason jars have a two-part top ― a lid with a rubber ring on the underside, which creates a vacuum seal (which is so integral for safe canning), and an outer band with screw threads that are reusable. The lids can only be used to seal once, but the jars and bands can be reused many times.
Mason jars are the go-to containers for preserving vegetables and fruits at home, but their commercial uses span a wide variety of products and contents. A generous mix of capacities, colors, and lid styles make these clear glass mason jars, and other models, a significant choice for packaging everything from soups to candles.
