This is a Staedtler mechanical pencil, the 925 25-09 Silver Series, with a 0.9mm lead diameter. Although it is new and unused, it was a display item in a store. The vinyl case may have scratches or stains. If you wish to have it delivered to a post office or convenience store, I will change the shipping method, so please comment in the comment section before purchasing. STAEDTLER Mechanical Pencil
