A beautifully designed weighted pen and mechanical pencil with The Pencil Grip attached. No loose weights or grips - just one solid piece. Looks like any other regular pen or mechanical pencil. Each pieces weighs 4.3 ounces (122 grams). The lead (2.0 mm) in the pencil is thick and will not break easily - it will take a lot of pressure! Pencil also includes an eraser. Replacement lead is available separately. The pen can be refilled with Parker Ink Refill, available at office supply stores.
