Thats awesome - how many rings does it come with? edit - when I pull the PS's off these in retail stores, sometimes they catch and pull from the rings - are these rings sharp on the ends? I dont want to worry about snagging a PS if I yank one too hard.
I am also interested but worried on the potential damage it could do to the squares. Does it leave an impression on the square where the clip was holding it, if it is let hanging for a long time? How easy is it to put a square on it?
It comes with 100 rings, which are designed ideally for this purpose. They definitely will not snag your square. The apply very light pressure, so they may leave an impression but it will smooth out in a few minutes. You should not yank on the square, but rather press on the clip which will open the clamp. It is very easy to use; a child could do it. I hang all my personal squares (which I call the "Private Reserve") on it and stand behind this product -- I would not sell it otherwise.
