HB Graphite MAXI pencils with large eraser, ideal for school and industrial use. 3.5 mm Ø lead. Ergonomic triangular shape. They are in the middle of the HB graphite hardness scale, recommended for writing and drawing. The lead offers a uniform stroke and is anti-break, thanks to the Lead Protection System (LPS) that protects the lead due to its adhesion to the wood. Wood comes from sustainable plantations. The MAXI pencil sharpener has a sharp and resistant carbon steel blade which makes it ideal for all varieties of pencils. It also has a safety blade system which prevents the blade from becoming detached from the body of the pencil sharpener. Ideal for school use. Transparent plastic.
