70mm (2 11/16") screw-on lids for use on wide-mouth 8 oz mason/jelly jars or standard 16-32 oz mason jars (will not fit 32 oz wide-mouth). The convenient 1-piece design has built-in rubber seal (plastisol) underneath the lid. The solid lids makes jars air-tight and the pop-down button makes a safety seal when heated.

Available in glossy gold finish (as pictured) or white.
