Description
When this solar-powered smart calculator was released by Sharp Corporation, it was the thinnest in the world! It comes in a blue velvet pouch, and was marketed heavily for its perceived elegance and sleek style. An advert from the time of release reads "outsmart everybody this Christmas", and shows the calculator carefully balanced in a crystal port glass.
