Technology of the strength, Stein structure. A frame supports a core from the inside. Therefore it is hard to compromise! Stein establishes a frame with the reinforcement silica in the inside of the core. For the structure that this frame supports the whole core from the inside, I realize the highest-level strength. It is the smooth totally new sharp extra lead which I write it and incorporated technology of the strength in in addition to taste. The case which turns a cover, and can pick up a core. ??Mechanical pencil extra lead ?? core diameter: 0.5mm ?? hardness: The length of the 2B ?? core: 60mm ?? core number: 40 ?? number containing: One
