Comes with an original case that is easy to use and store. Size: Width 236mm x Height 380mm x Thickness 69mm. [Colored pencils created for professionals seeking perfection]. We carefully selected high-grade fine particle pigments with excellent color purity and designed colors with high transparency and saturation. Unicolor allows you to express delicate colors just the way you want, with crisp and clear unicolor even for subtle neutrals and pale colors. Containing high-grade fine particle pigments and Mitsubishi’s unique newly developed special synthetic wax, it not only prevents annoying blooming, but also blends evenly onto various types of paper surfaces for beautiful coloring. Unicolor’s color core is highly abrasion resistant and has the perfect hardness for artwork. There is less chance of smudging your work with lead scum during production, and you can draw thin lines and paint with a comfortable touch. The wooden shaft that encloses the solid color core is made of California incense cedar, which is considered the best pencil material. The core is less likely to break and can be easily scraped without waste.
