I just pulled the box out of the trash. The machine on the box looks like a real machine to me; however, my machine is thicker than the one on the box and I only needed the pad that was attached, not the additional pads included. However, I could see that if your machine was thicker than 4 1/2", it might not fit. Hope this helps.

I had been looking for something along this line for a long time to aid in threading my machine; so for me it is the perfect solution.
