BRAUN solar calculator, with case. While many battery-powered calculators have been listed before, I believe the solar-powered ones are rare. Size: Body: 13.7 x 7.6 x 0.8 cm Case: 13.3 x 8 x 1.5 cm No instruction manual or outer box. There are no noticeable scratches or stains, but there is a small scratch on the lower part of the back of the body (image 3). Automatic off.
