I bought a laptop at a Bestbuy store, and the type of that is Inspiron 15 7000 (Dell). When I bought that, a salesman said that it will come with a pen. However, when I unbox it, there is nothing but the laptop and its charger. I just want to know is there really a pen inside it? If there is no pen, please tell me which kind of pen that could work with my laptop.
