ok, will post this afternoon. The thing that gave them away at first was the 1000's are a little duller in color than the real WTHC's. Then, I became aware that the texture was not that of a paulson. Too plasticky. Real paulsons if you push a stack together they will not slide around. These slide around. Other than that they are very very difficult to distinguish. The sound is almost identical, the colors and edgemarks are perfect aside from the yellow. Texture is what gave them away.
