100% Canterbury NZ grown premium ground walnut shell for use in cartridge case tumblers and vibrators. This walnut media is brilliantly clean, perfectly dry and approximately 1mm in grain size. Sold in 1kg bags this amount is 2 litres in volume (fills an ice cream container). Walnut media is a gentle abrasive that polishes up cartridge cases like new. To add a little extra OOOMPH to the media try pouring in a little Brazzo as the media is working. Only a small amount is required to turbo charge the mix.
