Good media
I somehow came into possession of quite a few old (ancient) coins. After looking up values, I decided that since they weren't worth much, I'd make some necklaces from them. they were really dirty so I first tumbled them with walnut media and followed up with this corn cob. they came out really clean and shiny.

Worked well
First time using corn, seemed to work fine. I'll probably still go back to walnut medi. Just wanted to try something different to me

Not as described
The description was a 12 pound bucket, I received a 10 pound bag. Media seems good though.

NOTE : Comes in a PLASTIC BAG and cardboard box - not a bucket.
If you need to store this or have humidity concerns, is does NOT come with the bucket shown.

I bought this to use in my rock tumber. I've struggled with tumbling fluorite and calcite and other soft stones. You Tube suggested doing very quick rough tumbles and then a DRY polishing tumble with this stuff as media to cushion the polishing powder. I think it worked very well - it cushioned nicely. I didn't have the greatest polish, down to my polishing power I think - but at least they didn't shatter!
