Mechanical pencil with 0.5 mm (LAMY M 41) lead, LAMY Z 18 built-in eraser with cleaning needle underneath the removable button. The Vista, with its transparent barrel and cap, and brilliant inner chrome workings, is clearly a great pencil. Its modern, hi-tech look and light weight makes it popular with note-takers. An excellent choice for a student you know, or see for yourself.
