Made using strong acrylic resins, Kitchen Blender herb grinders are designed to provide precision grinding within a light-weight, transparent package. The high level of transparency in acrylic allows you to see your dry herbs as you are grinding them. The magnetized lid ensures a tight-fit during the grinding process. The freshly ground herbs can be used or, if you choose, they can be stored in the air-tight storage compartment on the bottom of the herb grinder. Grinder Features: - Size: 2" - Made of acrylic - Magnetic lid - Airtight storage compartment - Sharp shark tooth design
