Transform your jars into your new favorite citrus juicer. Fox Run's metal Juicer lid is made from sturdy and long-lasting 18/8 stainless steel, specially designed to bring even more uses to your wide mouth mason jars. Please note, this item does not include any mason jar components (jar, lid, or ring). We recommend using an 8 or 16 oz. jar for best use. To use, apply some force to snap lid into rim. The reamer on top is great for lemons, limes and small oranges, and the featured screen will filter out pulp and seeds, leaving you with freshly squeezed juice in the jar! Snap, squeeze, chug! There's nothing fresher. Because, let's be honest, everything's better in a mason jar.
