I think ......... used to sell them but it seems like fewer and fewer US online stores carry them. Off the top of my head, the only store I know that's consistently carried a fairly large selection is CaliRoots (http://caliroots.com/system/search/s...asp?manuid=158 ) but they're Swedish. They do ship intl.
That's the part where I mentioned that they're Swedish but ship internationally. Like I said, fewer places in the US sell Edwin than internationally. Any particular reason why you only want North America?
