Smooth and comfortable writing experience.
In addition to the carefully selected graphite and clay, which are the materials for the lead, the pencil lead contains nanodiamonds for the first time in the world, making it possible to write both light and dark characters.
In addition, after baking, the pencil lead is soaked in oil to make it harder to break and to make writing smoother (oil processing), but it suppresses the pencils' own shine and makes the characters "blacker" and clearer.
The lines drawn are 10%* darker, and friction during writing is less variable, with a decrease of 10%* or more. * Compared to other conventional Mitsubishi products.
