This is the production jar with our own in-house designed Silva-Cap production cap.

You will see 2 supports for a pair of 14g or 12g silver rods.

There is an opening for the air agitator tubing that is supported, directly the air to the bottom of the jar. There's also an outlet hole for the injected air to escape.

We've sold thousands of these Silva-Caps. Everyone loves them for the simplicity and ease it will provide you in your home colloidal silver production.
