Thin, hexagonal pencil crayons with a graphite diameter of 2.9 mm. Natural wooden finish. They have a unique Lead Protection System (LPS), which increases the fracture resistance of graphite by sticking it to the wood. The wood is durable and soft, enabling easy sharpening. High-quality pigments in vivid, intense colors are resistant to light. The line made with MILAN crayon is soft, uniform with a clear shade. It does not create grooves or damage the paper. 100% of the wood comes from sustainable FSC (Forest Stewardship Council) certified plantations. Each crayon is imprinted with the color name in English. MILAN crayons comply with European and American safety standards. They do not contain phthalates, heavy metals and other toxic substances. They are safe for children.
