Well, our screen research screen came from the states but you never know, they may be French! The screen is actually a fine weave of special material. Gives the appearance of being flat and solid until you take a closer look. It is not perforated. I imagine there are many ways to solve the problem but I imagine this is the more expensive way. Certainly looks beautifully made.
