Store your shredded herbs with confidence. The Shredder includes neodymium rare-earth magnets that prevent escaping odors, accidental spillage, and dried out herbs. When you take off the top piece, it gives you a satisfying pop, telling you how closely each part is machined. The Santa Cruz Shredder also uses a nylon gasket around the edge to assure a smooth rotation without metal-to-metal contact. Not only that, the Shredder is scratch and fingerprint resistant because of its aerospace anodized protective coating.
