Reduce, reuse, recycle! Mason jars with two-piece lids are a classic time-tested choice for canning and preserving at home. Two-piece lids allow you to reuse the canning ring many times over while replacing only the recyclable flat plastisol-lined lid between uses. Prices listed include the jar and two-piece lid (ring and flat lid). To reorder just flat lid pieces, simply call our helpful customer service staff and we’ll put together your custom order.
