Barrel is 9" long by 2" dia, holds about 2 pounds of clay. Comes with 6 dies (one is a blank). This is for use with very soft clay.
Hint: Take care, when tightening the end cap. Cold clay seems to shrink the barrel and when you screw on the end cap with your superhuman strength, it makes it almost impossible to remove later. Once it has been used a few times, the cap is a little better seated and the problem goes away.
