Shape: Round is the most common shape, but they can also be square or oval.
Size: The size is determined by the diameter of the jar opening that it needs to fit. They can range from small caps for spice jars to large caps for food storage containers.
Closure type: There are several closure types, including:
Screw cap: This is the most common type. It has threads on the cap that screw onto the jar threads to create a tight seal.
