Each jar comes complete with 2 part lid consisting of a flat disk incorporating a seal (the lid) and a twist on ring to hold the lid in place for processing (the band).
Lids are recommended for single use only if the jar is heat processed using a water bath or pressure canner.
Bands can be reused.
For preserving, we always recommend using a tested recipe such as those listed in the Ball Blue Book.
