CASIO MS-20YC is a compact desktop calculator with a 12-digit LCD designed for everyday office and home use. Its navy housing and rounded form give it a friendly, approachable appearance while retaining the functionality required for quick arithmetic, tax and profit calculations. Dual power (battery and solar) ensures continuous operation and a slanted display improves numeral visibility when placed on a desk.

Embossed areas around the number keys and an oblique printed pattern on the upper key area add subtle accents. A rounded, slightly bold font improves legibility, and the slanted LCD enhances visibility of numerals from typical working angles.
