- This handheld electronic calculator has a black and white plastic case and an array of twenty rounded rectangular plastic keys. These include ten digit keys, a decimal point key, a % key, four arithmetic function keys, a clear key, a clear entry key, a square root key, and a total key. Behind the keyboard is an eight-digit purple LED display that seems to have a ninth character space. The on/off switch is behind the display on the right. A tag left of this reads: SHARP ELSI MATE (/) EL-104.
- At the top of the back is a compartment for a nine-volt battery. Text below this reads: ELECTRONIC CALCULATOR (/) EL-104. Further text reads: SHARP CORPORATION (/) MADE IN JAPAN BM. A paper sticker below the mark gives a list of U.S., Canadian, Swedish and Australian patents protecting the device. The latest American patent is 3621219, issued in 1971 and initially assigned to Hayakawa.
- The calculator has a leather or imitation leather carrying case with a metal snap and plastic edging. This case also has a hook so that it could be worn over a belt.
