I first saw them in the February 2008 issue of Non-no magazine, and from what I can read (which isn't a lot) they were arriving in Japan in April 2008. Six months later, they've finally come down this way.
I don't know which colour to get. There's the orange which is fantastic to go with grey; there's the yellow pair that will look amazing with parka-green; there's the green that can go with black; and finally, there's also the light-blue pair for the sake of my love of the colour.
Ah, I need to check first how much they cost.
