These are the suwarikko legs. They are very similar to L-01, and are the same length, but the slots for the elastic and the ball joints at the hips and knees are designed somewhat differently in order to allow for the cute sitting position. ('suwarikko' = 'sitting child'.) These legs can only be ordered in conjunction with B-04, the suwarikko body. This used to be a Sato only option, however as of September, 2006 it is available at all Tenshi no Sumika locations, including the LA Sumika, who added it at the time of LA Dolpa (late November, 2007).
