These are some very nice high-end peripherals for desktop computer users. The mouse is highly programmable and the keyboard is mechanical (MX Cherry reds), so it is super comfortable and quiet to type. The fact that it has backlit keys is also a plus for nighttime users.
Unfortunately, neither comes with a box, but the mouse is completely new and the keyboard is in awesome condition.

M95 Mouse: $65 (originally $80)
K95 Keyboard: $115 (originally $150)
Both: $160 (crazy good deal)
