Pentel Twist-Erase III Mechanical Pencil, 0.7 mm, HB (#2.5), Black Lead, Red Barrel

A 0.7mm mechanical pencil with a twist-up eraser larger than most, so it actually lasts instead of wearing down to a nub after a few corrections. Loaded with Pentel's own HB lead, never sharpened, with a protective tip that keeps the lead from snapping under normal pressure. Red barrel, soft latex-free grip.

This is the pencil built around the eraser as much as the lead, which says something about who it's for: someone who revises as much as they write, and wants the tool to keep up with both.
