In order to promote further cooperation between the two sides, it has become a common practice that we provide samples free of charge and you bear the freight.

But I think if you really care about it, you won't mind spending some sample fees. If it is provided for free to every customer who requires us to send samples, it will be a great burden for us. If we receive your formal order, we can refund the sample fee. We sincerely hope to get your support and understanding on this point.
