This is a Staedtler mechanical pencil, the 925 25-05 Silver Series, with a 0.5mm lead diameter. Although it is new and unused, it was a display item in a store. There may be scratches and dirt on the vinyl case. If you wish to use the post office/convenience store pickup option, I will change the shipping method, so please comment in the comment section before purchasing. STAEDTLER Mechanical Pencil
