Great for college student/math majors. Barely used, no scratches, no stains. I'm selling it because I haven't used it since my math class and I know how expensive these can be and how some teachers require only this type of a graphing calculators. It comes with a manual and unit-to-unit cable. See pics. E-mail me if you are interested or if you have any questions. I can ship it to you, but you pay for shipping costs (shipping, delivery confirmation and insurance).
