The Pentel Orenz features an innovative pipe tip that protects your lead as you write. You start writing without the lead protruding, and the pencil feeds your lead as necessary. This protects your super fine lead from breakage, and enables you to write with a finer lead than usual. The metal grip has recently been redesigned to be even more comfortable than before! The Pentel Orenz Metal Grip is available in both .2 mm and .3 mm tip sizes.
