Pentel Ain Stein Lead- Blue - 0.5 mm
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. STEIN stands for "Strongest Technology by Enhanced SiO2 Integrated Network".
High polymer and carbon in the lead form a honeycomb-shaped structure. Honeycomb structure is proved to be one of the strongest structure under force. The lead is also designed to be smear resistant lead, which is great for left-handed people.
Its counterpart in Uni is Uni NanoDia Pencil Lead, which is also famous for low-wear lead.
Each container contains 20 pieces of lead.
