The calculator has a black plastic case with eighteen plastic keys, sixteen of them square. These include ten digit keys, a decimal point key, four arithmetic function keys, a total key, a percentage key, and a clear/clear entry key. The on/off switch is on the keyboard, the eight-digit display behind this. The plug for the power supply is on the right side. A mark above the display reads: Radio Shack.
