This is the Canon "X Mark I Mouse",
released in 2010.

It is a unique device that combines
a mouse, a numeric keypad
and a calculator in one.

Canon has a long history
of making calculators,
starting with its first electronic calculator,
the "Canola 130", in 1964,
and that experience lives on in this mouse.

You can enter numbers and do calculations
while using your computer,
and even send the results to your PC.
There is a PC/Mac switch on the bottom.

It has been tested and works.
Mouse only, no other accessories.
There are scratches and marks from use.
