The Hario Mini Mill is a great travel companion, and it still uses those quality ceramic burrs that you'll find in the larger version of this grinder - the MSCS-2TB Skerton Mill.
Easily holds 24 grams of anything from fine espresso to a coarser french press setting. It's a plastic body making it quite lightweight and durable. A coffee enthusiast's must have when traveling.
