This is a soft polishing powder. It's a powder for polishing pots and metal ladles. Manufacturer unknown. It was purchased about 30 years ago when I bought a pot. It's unopened, but due to long-term storage, there are small holes in the vinyl, and the powder is leaking. I've reinforced it with cellophane tape where I could, but there are still areas that are not covered, so please consider purchasing with this in mind. I will ship it in a Ziploc bag.
