首先,我们将用一个内包装来装7套 spare part. 然后我们再用一个大的外包纸箱来包这个内箱.请注意:一个大的外包纸箱可以装3套内箱子.所以我们算出一个大箱子一共可以装“7套*3=21/20 套. 600套的话我们将用30个大纸箱来包装.请确认是否可以用这种方法来包装您的货物.
At first, we plan to pack these 7ea spare parts with a small box, then we will take use of a large box to pack this small box inside. BTW, one large box can contain 3 small boxes, in this case, it means one large box can contain total 21ea parts. In case of 600ea parts as you ordered, we can complete packing with 30 large boxes in this way. The question left now is I need your kind confirmation whether our scheme can work as above. Looking forwards to your feedback and thanks so much in advance.
