Kozo 3" Aircraft-Grade Aluminum Grinder

The Kozo 3" is a larger grinder made from aircraft-grade aluminum (Al 6061), built for people who grind more than a pinch at a time. A grip pattern around the body makes it easy to twist, a strong magnetic top keeps material from spilling, and sharp teeth grind flower evenly without turning it to dust. The tall mesh screen section holds a generous amount of ground herb and lets kief collect below. It is offered in nine colors, Black, Blue, Gold, Green, Pink, Purple, Red, Rose Gold and Silver, with the Kozo Grinders logo on the lid. The wider 3 inch body means fewer refills per session, though it takes more room than the 2 inch and 2.5 inch sizes.

It makes more sense as a home grinder than a pocket one. If you want to compare with other builds, our herb grinders collection covers sizes, materials and styles. Brush the screen section after use and deep clean with isopropyl alcohol when it gets sticky; our cleaning tools cover the supplies. A jar from our stash jars keeps a larger batch fresh.

Choose it if you prep bigger amounts and like a heavier-duty aluminum grinder.
