These gears have been pulled out of joysticks that have been rebuilt. Many still have use, some may be worn more then others, and some may just be no good. Selection varies, and every gear has been soaked and cleaned. I can't promise that every gear is decent. Whenever I rebuild a joystick module I just throw all the gears in the box. There's over 3,000 sets of gears so far. Every week more is added to the boxes. Some gears just may be no good. These are grabbed from a box when you purchase them. At the price point it’s like gambling. You might get some good ones you might not. If you don’t want to take that risk please don’t buy these then leave me negative feedback because you didn’t read the description.
