Interchangeable graphite leads from a leading Swiss manufacturer. Artists prefer a soft 2B pencil that creates subtle clouds and shadows. However, it can be stressful when hundreds of pencils are lying around the studio. How about using a mechanical pencil? Interchangeable leads give you the hardness of a sleek pencil—direct and much lighter for your bag. If your lead breaks while drawing, it's an absolute disaster that can set you back hours or even days. Make sure your leads are secure. These pencil leads come in a protective plastic box with twelve pieces each. This way, they can be neatly stored and won't get damaged. While they can break due to their softness, they are well protected in the box. These high-quality graphite leads have a diameter of 2 mm, making them stronger and more durable.
