These sturdy leads with a thickness of 3.2 mm and a length of 90 mm are available in two hardness grades: HB (universal medium hardness, ideal for everyday writing and drawing) and 2B (softer, for darker, more pronounced lines suited to details and shading). Each set is packed in a sturdy plastic tube that protects the leads when carried in a pencil case or luggage. These leads are compatible with thick mechanical pencils (3.2 mm), often used in art and technical studios. They offer smooth, smudge-free writing and perform well even during intensive work. They are a great choice for architects, designers, artists, and students who need to combine precision, comfort, and an aesthetically pleasing result.
