About This Product

The Casio PRIZM FX-CG50 Color Graphing Calculator is a calculator made for long days at a desk.

Casio's digital watches are famously indestructible for the money, a decade of battery life and a module that keeps time regardless of treatment.

Priced at $102, cheap over ten years, even if it doesn't look it today.
