Sounds like regular 4x4 inch Velcro. Not sure about the back to back part. Check out your local Home Depot/Lowes. The home shelving part of Target and even Staples. Lots of Velcro selection these days.

I go ahead and went to a place very closer to where I live that sell craft fabric stuff, I thought they closed, but still there lol, its been 15 years since I been here, I usually come here back in the day to buy fabric for headliner . Anyway they do have the heavy duty industrial velco tape, just perfect size I need. Thank you
