Hello, I would like a sample of black 5/8 and 3/4 black shiny biothane with the grooves on each side.  Also samples of the reflective in black in 1 inch if you have it.  I have bought from you before, but I do not know what the types of biothane are.  The best one for me is the 5/8 black that has the black webbing inside.  Thank you, Lorena
