Trackball Replacement 34mm Trackball only. I believe it was gunmetal black from an Elecom EX-G. (I'm not certain, so apologies if it's incorrect...) *Please purchase if you understand that this is a used item. Also, please understand that the storage condition is only based on amateur storage. Those seeking perfection or who are overly sensitive, please refrain from purchasing. If you have any questions, please comment.
