my mom had a cat named reefer in the 70's. i just had to share that. not only because it's hysterical, but because it sorta relates to this post. these glasses from factory 37 are made from recycled reef glasses, which make them super environmentally friendly. "the green glass company takes original bottles that are heading for the landfill and transforms them into these functional yet witty glasses." while i'm not super gung ho about the look, i do love the thought behind it. very treehugger, very cool.
