The lotion in the silver lidded jars were found at my local grocery store. They are Ball jars, called Classic Elite and are 8 ounces. I bought a four pack for just under four dollars.
Besides MidWest Bottle I found a place called SKS. I don't recall their full name. They sell for a bit less than MidWest depending on what you want. You have to buy a full set of 12 or 24 in the size you choose. I have not ordered from either place. Now that I know that I like the 8 oz size best, this is who I would order from so I can get a good price and have them on hand.
