These include ten digit keys, a decimal point key, a % key, four arithmetic function keys, an on/clear key, a clear entry key, a square root key, clear/clear total key, and four memory keys. An on/off switch is at the top left of the keyboard. Text to the right of this reads: SHARP (/) ELECTRONIC CALCULATOR. Behind the switch and this mark is an eight-digit LCD display. A mark at the base of the front of the calculator reads: SHARP ELSI MATE (/) EL-8133.
At the base of the back of the calculator is a compartment for two squat cylindrical silver oxide batteries. A sticker on the back reads: 88422037. Text molded into the back reads in part: ELECTRONIC CALCULATOR (/) EL-8133. It also reads: SHARP CORPORATION (/) MADE IN KOREA BM.
The calculator fits into a black plastic wallet. Also in the wallet are an instruction manual, a pad of paper, a sheet of instructions for ordering memo pad refills, and a sheet warning that the display is of glass. It reads in part: “Do not put your calculator in the back pocket of your pants as it may be damaged when you sit down.” The wallet, in turn, fits into a cardboard box marked at one end: SHARP (/) EL-8133. A price tag on the box reads in part: $17.95.
