Botgrinder's 4 layer, 3 chamber, 2.4inch diameter aluminum herb grinder.
This is my favorite type of grinder, its works well, it has the compartments i need and its not $50.
I call this the "gas station grinder" because its similar to one you can pick up at any corner store in philly, only this one is alot nicer.
Put it in your flight bag, toss it on your tool kit, this grinder will hold up your abuse and it has my logo so everyone will know you aint about no bullshit. this is the botgrinder!
