The Mitsubishi Dermatograph pencils are like upscale versions of your typical grease pencil. Available in several bright colors, these soft colored pencils are perfect for writing on glass, metal, plastics, ceramic, vinyl, cellophane, and marks can be removed from any non-porous smooth surface. The paper wrapping can be removed by pulling the inside thread, which will in turn expose more of the soft colored lead. Several colors available.
Pencil dimensions: Approximately 6.9 inches (17.5 cm) long and 0.3 inches (8 mm) in diameter.
