Also known as the London Rectangle, these clear glass square jars will give your product a fresh new look on the shelf. The square design offers four panels for labeling, leaving ample space for customers to see the quality product housed inside. Fill these stylish jars with gourmet foods such as jams, jellies, mustards and spreads or as a stylish container for handmade bath salts and scrubs. These square 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. Gold metal lug caps with acid-resistant liners included.
