Lortone 33B model tumbler. This unit comes with two - 3 pound barrels.
The 33B is an excellent tumbler for beginners, offering flexibility in a small footprint. Dual barrels allow for tumbling rocks of different hardness levels, or at two different stages of progress.
We often suggest it if you have a young rockhound in your life; you can each have your own barrel without your treasured finds getting mixed up.
