The Cosmic aluminum grinders set themselves apart from the competition in several ways. From their single aluminum piece it is crafted from, in the USA, to it's stainless steel sifting screen and beveled edges to stop your material from sticking. To complete the package it even has a storage compartment at the bottom along with a magnetically sealed top for additional storage and to help prevent spilling. The medium size measures about 53mm (2 inches) which is a little smaller than your average size grinder.
