4 Piece CNC Groove Grinder/Sifter
Featuring innovative coaxial turbine technology, Groove by Aerospaced has changed the nature of grinders as we know them. Through its proprietary design, Groove requires minimal material preparation and delivers a coarse grind, naturally separating unwanted material for optimal consistency.
How it Works
Remove top lid and place material on grooves, replace lid and then rotate back and forth until the material is fully ground. Open bottom chamber to access your freshly-ground material.

This is an excellent grinder. It's sleek. Easy to use and avoids that nasty stickiness that other grinders can develop. The magnet makes it on put, and it grinds great. I am happy with this.


I am in love with this grinder in every way possible. Not sure why u put black on top of Rasta.. but ok.. the amount of kief that I collect is insane.
