This is a fake / faux snakeskin case / wallet with an installed Unisonic CL 1160 electronic calendar (case is designed to hold this, which is encased in plastic in custom slot).
it has plastic flip sleeves to hold business or credit cards and a pen holder.
case dimensions 6 1/2 in x 3 1/2 in.
calendar calculator is 3 1/2 in x 2 1/8 in and about 1/8 in thick.
it seems to need a battery, and there is a screw-out slot in the back of the calculator which looks like a battery port.
there is a operation instruction card behind the calculator.
Unisonic was manufacturing calculators with model numbers starting with "LC" c 1980, although I can't find any online reference to this instrument, which seems to be exclusively a calendar/alarm.
