Allright. I am sick and tired of people saying they bought a 6x frenel lens. No matter what you here on ebay, there is no such thing as a 6X fresnel lens that is 7"X10". If you go to the 3d lens web site , they are a manufcturer of the 3x fresnel lenses. Acroding to them, it is not possible to make a 6X on such a large sheet. If you are looking for large *** fresnel lenses to make a projector, try this site
