The Pentel Graphlet PG500 is a stalwart of the Pentel drafting pencil range. Standard issue at many major Japanese corporations, it's been around for many years. Simple straightforward design with a fixed sleeve, textured metal cylindrical grip area over a tough hexagonal plastic barrel. It features a removable metal pocket clip and a lead grade indicator (B-3H, including F). The eraser is located under the cap. Available with 0.3mm, 0.4mm, 0.5mm, 0.7mm or 0.9mm lead. We recommend Pentel AIN Stein replacement lead. Z2-1N eraser refill is available.
