The Pentel Graph 1000 is a premier mechanical pencil designed for drafting professionals. Its long, slim sleeve gives it precision when running along the edge of rulers and templates and allows you a view of what you’re drawing. An all-brass three-jaw clutch mechanism provides exceptional lead support. Each click of the top-knock button extends a length of lead equal to the diameter of the lead. Specially-weighted to bring its centre of gravity close to the writing tip, the Graph 1000’s cylindrical body is comfortable to write with. The rubber-insert grip further enhances writing comfort. The Graph 1000 also features a removable metal pocket clip, a replaceable eraser under the cap, and lead grade indicator in the push-button. It is ideal for professional drafting and for sketching, drawing, and everyday writing.
