The Sweetleaf aluminum pocket size grinder was designed with portability in mind. It's made of a durable aluminum but still light weight enough where it won't weigh you down when carrying it around in your pocket. The small size measures about 50mm (2 inches) in diameter and the strong aluminum build makes it one of the best grinders you can get to carry with you when you are out and about.
