The Lipstick is their 'flagship' formula, retailing at a breathtaking £40 in the UK and $55 in the US. (Is there some kind of definite article mark-up?) The patter promises that the lipsticks improve the look and condition of lips both upon immediate application and boost their capacity for self-repair with prolonged wear. But more to the point, The Non-Blonde rates it as one of the best around.

Here's a picture with flash taken a day after swatching, when all the creaminess has gone:
You can see the golden micro-shimmer more clearly in some shades than others, but this is mostly just a quirk of the lighting. 10 Hiwada, is the only shade with visible shimmer once applied (see how much more densely-packed it is?). The other shades really do just leave a dimensional sheen on the lips, even to my shimmerphobe eye in direct sunlight.
In the UK, Kanebo Sensai has counters in Harrods and Selfridges.
