Selling a used, but mint condition (literally no scratches or marks on the calculator) HP 50G graphing calculator for $50. Comes with the leather (perhaps fake leather) case that they come with. The case has a few imprints on it.... basically just lines from things that it was against. The imprints are shown in the picture. Willing to entertain reasonable (but not low-ball) offers.

HP graphing calculator, TI-89, TI-86, TI-84, TI-83
