Looks like sturdy metal tripod legs. Got my long selfie stick up. When closed, this offers a good grip, but the legs do not meet exactly flush. It's a bit out of the way and you have to fiddle with it. One of the legs is slightly looser than the others. I tightened the hex head but it did nothing. It's nice of them to turn on the hex key. So I loosened it a hair and now they all stretch and fold the same way with the same less tension. I'll update if I come across a broken screw as many do, but this is meant to be an updated version. When they go on sale I'll probably buy a few more because they're metal and longer than most legs.
