The 8 oz clear glass jelly jars are available with 70G gold metal printed plastisol-lined caps. The metal caps are printed in black with the message "Button Pops up when Original Seal is Broken." To create a vacuum seal, the glass jar and product must be heated to recommended temperatures, softening the liner. As your product cools, the plastisol liner solidifies and creates an airtight seal with the glass jar.
