The STAEDTLER graphite 778 mechanical pencil is a precise writing tool that is ideal for technical drawings, sketches, and notes. With a lead diameter of 0.5 mm, it allows for fine and detailed lines, while the fully retractable tip ensures the lead is protected when the pencil is not in use. The spring-loaded lead provides even pressure distribution and a comfortable writing experience. The hexagonal grip offers ergonomic handling and prevents the pencil from rolling away. Additionally, the graphite 778 features an integrated eraser and a practical clip, making it a versatile companion for everyday use. The shaft made of durable plastic in classic black gives the pencil an appealing look and longevity.
