Measuring 3.25"x2.1"x.60", this is a laser tracking wireless mouse featuring an image of Spiderman swinging just slightly above a rooftop landscape, wondering why Aunt May decided to start charging rent!  This cute little Spiderman 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!  Spiderman loves the computer. Although, he wonders why it doesn't toast bread.
