Great for camping, power outages, or your off-the-grid cabin in the woods.
A perfect gift for the coffee geek in your life.
The cup, lid, and handle are made of stainless steel. The grinder is cast iron, which can rust.
If the cast iron part gets wet, dry thoroughly and quickly to avoid rust.
The grinder will come set to a very fine grind.
To adjust the grind size:
Remove the gold nut, the handle, and the round piece under the handle.
Now screw the gear shaped piece up and down the threaded rod. You will see the 2 pieces of the grinder moving closer or farther apart.
