Our 19 oz Clear Glass Round Jars are uniquely shaped with rounded sides with flat panels on the front and back of the jar, allowing for easy labeling and branding. This jar will stylishly house your jellies, jams, mustards and more. Made with flint glass, this jar is crystal clear allowing you to easily see the contents inside. These round glass 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. The included lug caps have an acid resistant liner that draws a vacuum on any lug-finish jar. Jar made with high quality Italian glass.
