Hi guys i'm back with a bottle. I have been gathering tons of info from the people on this sight. I have a blue bottle that was found in my dump. It is square in shape. About 5 inches tall and 1 1/2 inches wide and has a circle on the bottom with an M or W on the bottom. I'm new but most of the blue bottles on this site have been pill or poison[8|]?that i have seen. Know where i can start my search???
