Zebra DelGuard mechanical pencil, 0.5mm size. Color is blue. Unopened, so the body has not been checked. Feature 1: Protects the lead from breaking under any angle or amount of pressure while writing. When strong vertical pressure is applied to the paper, a spring built into the shaft allows the lead to escape upwards, preventing breakage. When strong diagonal pressure is applied, the metal parts at the tip automatically come out and wrap around the lead to guard it.
