JE-12E-WE Ergonomic Compact Desk Calculator


ALL NEW CASIO JE-12E-WE (MEDIUM SIZE), High-Quality Ergonomic 12-Digit Desk Calculator

Ergonomically designed Calculator for right hand users.

The keypad is configured in an innovative staircase design, with 3° inclination from right to left side.

Compared to conventional desk calculators, this causes less underarm torsion and hand wrist rotation, as it adapts to natural finger / hand posture. The staircase key shape enables perfect vertical keystrokes and thus eases the key typing, lessens burden and helps avoiding Repetitive Strain Injuries. The staircase design keypad causes less strain of the pronator teres muscle, the extensor carpi radialis muscle and the flexor carpi radialis muscle

The keys are extra easy to operate, and the key caps are ergonomically shaped (concave / convex) and are extra shock-absorbing for less fatigue of the fingers even in full-day operation.
Silent Touch + Durable Anti-fade Plastic Keys: Markings do not wear, as being injected into the key.


Reliable & Durable High-Quality CASIO Desktop Calculator Aluminium Front Plate and extra large Anti-slip Rubber Feet.
Solar/Battery powered - solar powered when light is sufficient, else battery powered, with Auto Power-Off. Battery compartment easily accessible for replacement.
