Glass paragon jars are popular for their versatility. Featuring wide openings and slender bodies, these jars are easy to fill while optimizing shelf space. Paragon jars are often used for jams, sauces, herbs and spices. These paragon jars feature a lug finish. A lug finish consists of several tapered ridges designed to mate and require only a partial turn to seal the cap. Jars include gold metal lug caps with acid-resistant liners.
