The Mini Mill 4-part metal herb grinder is proof you do not need a big setup to get the job done. At just 1½ inches wide, it slips into a pocket or pouch without even thinking about it. The zinc alloy build gives it a sturdy little weight, and the assorted colors keep it from feeling plain.
This 40 mm grinder uses a classic 4-part, multi-chamber design so you can grind up top while finer material settles into the lower chamber through the screen. It helps keep your prep more organized compared to a simple 2-piece. The textured edge also makes it easier to grip and twist, especially for quick dry herb sessions on the go.
