I use Williams Mug Shaving Soap. In February of 2009 (see USMA #43258), I wrote
them because they did not dual label their net contents as required by law. It
was labeled 1 3/4 OZ only. They sent me an acknowledment, saying they would
look into it, but making no commitement.
Last year, I had to buy a new box. They still hadn't changed, so I assumed
they had ignored my letter. Today, I had to buy another box. It is labeled
NET WT. 1.75 OZ. (50 g).
It's a small thing, but it is my first letter about metric packaging that has
ever resulted in a product change. Woot.
