Rest your mitt on the Wolf Spider Computer Mouse and add a thrill to dreary computer work. Yes, that’s a real wolf spider embedded in the plastic mouse—dead, of course--and the mouse lights up to cast a glow on the dangerous insect! Faint-hearted, beware! The Wolf Spider Computer Mouse measures 4.13" x 2.25" x 1.5" and fits any computer with USB connections. Note: Because each insect is real, there may be variations in size and color.
