The Kannastor Aluminium Grinder has a transparent lid, so you can actually see your herb being ground.

It is built to last with strong, sharp blades. There is a magnet in the central pillar, to keep the lid in place.

These grinders come in a protective drawstring bag, with a guitar pick which can be used as a cleaning tool.
