You can add a note to your order for color choice, or message us after you place your order to let us know. We'll just send you a black or gray if we don't hear from you. The calculator conditions vary, all of the screens will be very usable but may show wear. Some calculators may show signs of previous ownership, such as a name or sticker on the back.
