This is a brand new wired mouse that has been used once to test to make sure it works. It lights up when plugged into a computer or laptop when it's in use. It switches between colors, but as far as I know, it's not controllable. ~~~~~~~~~~ • I’m selling things to free up space in my parent’s house • I ship through UPS (which starts at $7.99) to have items shipped out the next day • I am willing to ship through USPS (which is usually cheaper).
