英语翻译我想前天给你的邮件没有表述清楚.因为我们仓库里面的纸都是用于纸杯的,所以质量非常好.再你没有答应付样品费的前提下

I think that the mail sent the day before yesterday didn't express clearly. The paperboard in our warehouse is used for making paper cups, and the quality is very good. Because you didn't promise to pay us the sample fee, we planned to make the sample with this paperboard. However yesterday you insisted that the sample must be made as yours, and you could pay for the cost. In this case we could purchase the paperboard from the manufacuturer who produces the paperboard and make the sample layer by layer according to yours.
这是非常准确的翻译了.
