 I ordered some bodyline clothing and I ordered shoes(shoes178). It has been stuck at customs for a week and a half. T.T I finally thought everything was done, so they could send it to me, but they requested footwear details. They are asking me what percentage of weight of entire article : a.fiber b. plastic/rubber c. other. They are also asking me percentage of exterior surface area of upper: a. leather b. plastic/rubber c. other. So when I read this....O.O??? How am I supposed to know the percentage? T.T Please help!
