Black Nunchuck Wired Controller Compatible with Nintendo Wii

This nunchuck, sold as used, arrived in new condition in a retail box. During inspection, I carefully compared it to the nunchuck provided with my original nunchuck. I was checking to see if it was a knock-off. I noticed the connector casing had a tiny bit more separation gap towards the end. It almost seemed to have undergone a small amount of heat or sun damage. But, I squeezed it and tugged on it and the damage did not seem to have compromised the integrity. I also tested the nunchuck in game play and everything worked fine.
