I'm looking for some place that sells one way glass. I only need a few small pieces, about 3"x3" or 4"x4"...... I can't find any place online that sells this sort of thing.
Does anyone know of a place???

Also, is one way glass always like a mirror on the outside, or can it be different colors? Say, Black for example?
I want to use it for security cameras, and black would be perfect, as long as when you see out its not dark or tinted. I want it to be clear when looking out of it....

Thanks
