A brand new computer gifted to me from Jarir, comes with its invoice. The computer is a Surface model, includes a pen, and can be converted into an iPad by detaching the keyboard. I'm selling it because it was a gift from my father and I don't need it. It's excellent, has many great features as mentioned by Jarir. The seller can request the invoice; the price differs. Absolutely non-negotiable on price drop, as I swear it hasn't been used for even a month, and comes with the original invoice. It was purchased for approximately 4400, including its bag which cost around 150. Selling price is 4000, absolutely non-negotiable.
