16 oz. Glass Jars, Clear Glass Mason Jars w/ Silver Metal Plastisol Lined Caps (12 Jars)
The clear glass mason jars are available with 70G silver metal plastisol-lined caps. To create an airtight seal the liner must first be softened. This is done by heating the container to the recommended temperature. The plastisol liner then solidifies as the glass jar cools, which creates a hermetic seal. When the container is opened, the tamper evident button on the cap will pop up indicating that the vacuum seal has been broken.
