The packaging for the Corsair Sabre Optical RGB is typical of a mid-range gaming mouse. It features a flip lid to give you a look at the product (good for the five of you that still buy off the shelf) and there are listings of all the most important features.
The back and interior of the box show some of the available lighting options, though thanks to Corsair's back-end software for its RGB peripherals, you will be able to make much fancier effects if you choose to.
The manual and warranty sheet are pretty typical, offering some quick set up information and instructions on what you should do if in the unfortunate event that your new mouse should break down.
