Case tumbler medium?

[Elwellaxe]

I have a Thumlers Tumbler, I only used one bag of walnut shells,lasted years, I used to wash it & spread it out on newspaper on a sunny day to dry, worked a treat, now I use long grain rice, yes, you guessed it, the cheapest, it might not get a shine like walnut grounds but it gets the dirt off. I don't know if it would work in a vibrating cleaner but for around 75P give it a try.

P.S. If your really tight you can wash that also.

You should be able to get it from a local supplier/ pet store
