Mitsubishi Pencils Dermatograph Colored Pencils feature special leads that can be used to draw freely on glass, metal, plastic and so on, which is difficult to write with ordinary colored pencils.
In addition, the core contains wax, so it writes smoothly and does not easily scrape the lead.
The core is wrapped in a thin paper so the paper can be removed for the lead out.
Since it can be drawn on a variety of things, it can be used not only for illustrations and coloring pencils, but also for job sites.
Set of 12 colors includes brown/red/pink/orange/yellow/white/yellow/yellow/green/water/indigo/purple/black.
