For your consideration is a Vantage Point Speaker Mounts.  I'm not sure if the items have every had any actual use, but they appear to be in good usable condition.  I had to remove them from the packaging for more efficient shipping.  There are 5 mounting brackets, and the hardware is still sealed in the original bag.  The item also comes with the original install instructions seen in the photos, but no plastic packaging.  

The item ships with Priority USPS.  Please let me know if you have any questions or would like any additional photos. Thank You!!
