Grit is the magic stuff that wears down the sharp edges of rocks during tumbling. Without grit or other polishing media such as ceramic pellets or walnut shells, tumblers would take much longer to accomplish an even polish. Buy the right grit for the job and your tumbler can also burnish metal and polish glass. Itís magic!
