Professional mechanical pencil from Uni Mitsubishi Pencils in Japan. The pen has a solid metal grip and a plastic ring that acts as an indicator of the lead hardness. Very practical if you use several different hardnesses when drawing. The pencil is delivered filled with 0.5 mm HB leads and is of course refillable. Like most mechanical pencils, you'll also find an eraser at the top (which is also refillable).
