This is a two-socket adapter. I am selling it because the size didn't fit my car and I couldn't use it. The packaging has been carelessly opened, so the top is tattered. The clear plastic mold inside has been discarded and is not included, but I plan to pack it with other cushioning materials for shipping. Please read the instructions on the back of the package carefully and make sure the size is correct. If you have any questions, please leave a comment.
