There is zero plastic in our hemp grinders. We use all-natural hemp with a hemp-based binder, so you can feel good about throwing it in household garbage. The grinder itself is 100% biodegradable. This hemp grinder is extremely durable! After nearly a year of hard labor, our test models did not show any sign of slowing down. Design to give you a consistent fluffy grind that Santa Cruz Shredder is known for. New Color Hemp Shredders are made with natural dyes to keep these completely biodegradable. If you would like to complete your grinding arsenal, add a stick of Hemp Shredder Grease to lubricate your Shredder.
