A slightly cheaper alternative in the grinder world, but, well worth a look.
This super strong polycarbonate grinder has small pyramid teeth which are great for buds and leafy material, but are also strong enough to grind through solids as well. Not only that, but it will grind through coffee beans and pepper corns!!
On one side of the grinder there is a built in airtight compartment in which to store your non-ground material, or a very useful in-between from grinding to using.
Easy to use and clean, you can even put it in your dishwasher.
