This is the largest version of the innovative Aerospaced Groove 4-part metal grinder. It has a 3-inch diameter for a big capacity while still remaining just as portable and durable as the other versions.

This grinder stands out with its coaxial turbine grinding technology, which delivers a light, feathery grind consistency. It’s easy to use thanks to the grip-friendly edges and a magnetic lid. The pollen catcher compartment collects the finest bits from your materials, and the smooth finish makes it easy to collect pollen once you want to enjoy it.

The grinder is completed with a decal on the lid and is available in a selection of colors.
