Unlike conventional color pencils that have the fragility characteristic of wax, these pencils have a dense and hard core, giving them the following features: ・The durable and smooth core is ideal for drawing clear lines of the same thickness. ・The highly light-resistant pigments prevent fading and discoloration from sunlight. ・Because they are non-water-soluble, there is no smudging or bleeding of the drawn lines. They can be used for various purposes, such as filling in graphs, correcting blueprints, writing on design drawings, and educational materials.
