Made from assembled recycled wood.
Made by the "joint construction method" using wood scraps: parts that cannot be used due to "splash" and "chipping" of the slats (processed board material that is the material of the pencil handle) were cut out, and the remaining pieces of usable wood were joined together.
They use mature micrographite mine.
They're great for writing.
