FORJARS canning lids and rings ensure an airtight seal. The regular mouth, 24-piece set helps preserve goods using water bath, pressure, steam, or vacuum sealing methods. With 12 lids and 12 rings, the BPA-free design also resists rust. American-brand recognition, paired with third-party validation, makes this a reliable choice for home canning. Each lid provides space to write the contents and date.
