So I order 10 of these and I honestly can't figure out why I need 10. Before you ask then why did you order 10 I got a good deal on buying 10 instead of the 3 or 4 I need. So on Adorama they are roughly 31.00 shipped I was thinking $25.00 shipped. These look new and new can be I will take a few snaps later tonight and post of pictures if needed. So if interested let me know.
A few things these could be used for is photography stuff of course but also could be used to mount a camcorder on a roll cage with the purchase of a little stud to attach the camera to If thats your need I will direct you to the right spot for the stud needed,
