Calculator CASIO SL-310YC pocket basic, 10-digit, battery and solar, tax & profit functions, black

CASIO SL-310YC is a pocket-format basic calculator with a 10-digit LCD, powered by both battery and solar cells. It combines a compact, rounded body and easy-to-read rounded font with basic financial functions — tax and profit calculation — to support everyday arithmetic at home, in the office or on the go. The model is available in several color options and features flat keys with rounded corners for comfortable operation.

Advantages

The rounded form and layered back make the calculator comfortable to hold and give it a friendly appearance. Embossed key areas and an oblique printed pattern on the upper key zone add subtle accents to the design. A slightly bold rounded font improves legibility, while the flat keys with rounded edges enable smooth touch operation. Dual power (battery and solar) provides reliable operation in varied lighting conditions.
