Walnut Shell Fine 1kg

1kg packs of crushed walnut shell for achieving fine polish on delicate surfaces. The small size and irregular shapes of the material can get into fine crevices in jewellery pieces. Walnut shell is very soft on surfaces, is durable and reusable and can be used in both barrel and vibratory tumblers. It is non-toxic and biodegradable. Unlike steel and ceramic shot, walnut shell is used dry, and can be used with various polish pastes/compounds.
