Grind to perfection with a Tsunami Sunken Top grinder. This 4-piece grinder is just 50mm, so it’s small and portable. Take it on the go in a purse, backpack, or even a large pocket. The lid has a sunken shape that looks like a bowl on the top. This minimizes the space in the top grinding layer, making the ground product drop through to the next chamber faster. This has a bright metallic blue finish.
