Microsoft XBOX360 original wireless handle. Wired handles are generally assembled with plastic core large mouth three-color mushroom heads, which are often used on original XBOX360 original handles or assembled plastic core rocker handles. The new mushroom head will be a little tight when installed, just align the rocker core with a little force and click in. This product is suitable for plastic core rocker. Iron core rocker is not available. I hope the buyer will disassemble the handle for comparison when shooting. There is a picture of the matching rocker below. So as not to take the wrong photo and waste your time and postage!
