USB-connected red trackball, made by Kensington. - Brand: Kensington - Connection Type: USB - Ball Color: Red - Design: Trackball Thank you for viewing. I am selling this because I repurchased a wireless type. I have used it for about 2 years after purchase, but there are no problems with the operation. The items shown in the photos are the included accessories. I will disinfect with alcohol, clean, and pack the item before shipping. I will do my best to make it as clean as possible, but please understand that it is a used item. If you have any questions, please feel free to ask.
