This ‘BL’ Aluminium Grinder 4-part anodised Violet with and with screen is CNC machined and is made from anodised aluminium with diamond shaped teeth. It comes with a magnet to keep the lid secure and a nylon friction ring to ensure friction-free grinding.
The anodising process changes the metallic surface of the aluminium into a robust protective coating whereby the natural coating thickens up to 0.03 mm. The surface is about 8 times harder than raw aluminium, protects against mechanical effects and is resistant to weathering and corrosion
