With delicate neutral colors and pale colors if you have clear and clear unicolor you can have delicate color expression as you wish. High-grade fine-particle pigments are compounded with Mitsubishi's newly developed special synthetic wax which is not only less likely to cause annoying blooming but also blends seamlessly with various types of paper and colors beautifully. Unicolor cores have high abrasion resistance and are the best hardness for artwork. There is little contamination of the work with the core waste during production and thin lines and painting can be drawn with a comfortable touch. The wooden shaft that wraps the solid color core is made from California incense cedar which is considered the best pencil material. The core is hard to break and can be cut easily without waste.
