Smart Crusher® is the highest quality grinder available! Precision machined from solid anodized aerospace aluminum and polished to a flawless mirror finish, it is air tight, portable, and includes an indestructible stainless steel screen. Razor sharp cutting edges that will never dull, specific size micron mesh stainless steel screen that will never clog, and the weight and quality of the aerospace grade aluminum used, set this apart from imitators. This is made up of four separate parts that work together. The lid fits onto the grinder with the assistance of neodymium magnets, keeping the lid firmly in place but allowing for the grinding movement.
