i always choose SAL, 7 times, usually takes 7-10 days (i'm in shanghai, not far from japan), and every package has good looking, no any damage. HLJ never let me down. maybe your local post service problem?
btw, once i ordered a set of 1/700 us modern carrier fighters(1200 yen), they said it has clear parts(limited edition, 1600 yen) but actually not, wrong picture they put on web. after i told HLJ about this, they apologise to me and give the right information on the webpage soon. the fee is right.
