2.0 mm leadholders are a required tool for any artist or design school student. The Uni-ball leadholders featured here are high quality (as its brand name conveys) and dependable. Since Uni-ball is famous for their wooden pencil line, it makes sense that their drafting tools would be of the same high level grade.
B, F, H, and HB lead refills available. Lead holders are conveniently colored to indicate lead hardness.
