Here's the answer I got to the questions.
To answer your questions:
What size containers are the gourmet sea salts?
All our sea salts come packaged in convenient wide flip-topped filled 3 oz. containers. Net weight varies by product. Containers are reusable and recyclable. -For example, the Hawaiian Red Alaea Sea Salt weighs 4 ounces while the Australian Murray River Pink Flake Sea Salt weighs 2 ounces, both in the same size container, due to moisture and mineral content.
How do I know you are operating from a properly licensed and approved facility, and not someone's spare room? where are you located?
We are an internet only business based in San Francisco, with a warehouse in Alameda. We are a fully licensed business, as are all our suppliers and growers, and vend at local certified farmers markets in San Francisco and Marin.
Hope this helps!
