Pentel Ain Stein Lead is the latest generation of lead produced by Pentel. Ain Stein lead is not the same as regular lead in the market. It uses the high polymer for the first time.
High polymer and carbon in the lead form the honeycomb-shaped structure. Honeycomb structure is proved to be one of the strongest structure under force. This is the first time similar technology is used in lead. Experiment shows that Ain Stein Lead is 10% stronger than previous generation.
Ain Stein lead is not only stronger but smoother than previous generation due to the honeycomb structure. The box of the lead is environment friendly. 92% of the box is made from recycled material. Ain Stein lead has a rotation structure at the cap, which prevents the situation that the cap is lost by accident. The lead can be achieved by simply rotating the cap.
