Our glass quad jars will give a artisan look to your jellies, jams, mustards and spreads. This jar will stand out on the retail shelf at specialty and gourmet food stores or on display at local farmer 's markets and festivals. These quad jars have 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 a gold metal lug cap with plastisol liner.
