Basic Calculators,Compact Desk Type JE-12E-WE Compact Ergonomic Calculator

Say goodbye to hand cramps and hello to comfortable right-handed finger placement. The new three-degree step key structure is designed to match the contour of natural hand placement. To achieve this design, Casio collaborated with Japan’s National Institute of Advanced Industrial Science and Technology to analyze the effects of prolonged use on the hands and fingers. The keys on this calculator retain a vertical keystroke direction to maximize comfort during extended periods of operation.
