To be clear, these are printed sheets in a cobblestone pattern. After setting them up on my railroad I ultimately decided to rip them out for two reasons: the sheets are way too green in color and I decided I wanted a full 3-D, tactile look and feel to my cobblestones. On the plus side, the pattern that is printed on the sheets is quite clever in the way it allows you to assemble them together without seams and in a non-repetitive manner. I think if I had used them on a smaller scale (i.e., roads that were only a couple of inches wide) they would have been fine. Also, the sheets are somewhat reflective but I'm pretty sure that would go away with a coat of matte spray. Green may be fine for a European look but I'm modeling the New York Central RR on Manhattan, and it just isn't right for me. The product is fine, so I recommend it under the right circumstances.
