.
My two rolls of toilet paper arrived today and on looking at them the edges are woven in. It is not a cut off edge.
It looks and feels like a nylon strap only a little smoother on the backside that is. The front side looks like aluminum foil.
Or did I say that backward and the aluminum foil side would be the side going against the hot?
I have never rapped any exhaust pipe in the past so this is new to me.
