These come as a pair and allow you to connect original intellivision controllers such as the Sears Super Video Arcade Controller or the Intellivision II (and the modern Cote Gamers Long Play) up to your Intellivision Flashback (Ultimate or stock). They are form fitted to attach to your Flashback. Very straightforward. Solid PCB design for long lasting performance.

NOTE: This is just for the pair of adapters. This doesn't include the flashback system nor does it include either of the intellivision controllers. Just to be 100% clear :)
