I had received by mail this pair of earphone directly from China, the only information I have is the address on the box as: OFWIN, Road No 222 longqiao chengxiangqu Pu TianSHi FUJIAN 351100 CHINA
I did spell the same way the address is on the box, It was sent by airmail postage paid, china post.
I will keep the box intact, and possibly bring it to the sheriff dpt. for advice
