Measuring 3.25"x2.1"x.60", this is a laser tracking wireless mouse featuring an image of Wolverine with claws unsheathed and bloody, leaving behind him a slightly disturbing scene.  He does kill people, you know.  This moderately gory little Wolverine mouse also features an RF Transmitter for a quick, accurate connection and 2 buttons with a scroll wheel/ third button. This baby is Mac and PC compatible, runs on 2 AAA batteries (included) and goes great with one of our superhero themed keyboards, or works well as a portable mouse for your laptop!  Wolverine only lets us take his picture right after he guts a pig.  We don't question it.
