Muji
Seeing as Muji has become quite a large company, it is about time that they get a real store in the US instead of having other boutiques carry their goods. Although Momastore has sold a small selection of Muji products for several years, it was only until recently that they set aside a part of the store exclusively for Muji items! I guess it's the closest that anyone will get to Muji in North America ...
My latest Muji purchase was a set of simplistic cardboard speakers. Even though they are not incredibly functional, they were fun to build and cool to look at. And the sound quality is certinaly not terrible (or at least it is quite a bit better than my laptop speakers ... )
