Many big brand eyeglasses are printed with the mark of "made in china" because China has their branching companies. About the Arnette sunglasses which should be made in America, they may be made in China. But I am not sure. If you have one with the mark of "made in china", you could ask the detailed information from the clients in the franchise store where you buy it.
I am not sure. But i heard that arnette sunglasses are in American. But i still see some arnette sunglasses sold in China. Anyway, i think the arnette sunglasses are cool. If you want to buy a pair, you can go their official websites http://www.arnette.com/. Besides, i also see some at http://www.zappos.com/arnette. Hope this help you. Good luck.
