I heard that von zipper sunglasses are brand of America. If you want to buy a real von zipper sunglasses, you can go their official websites. https://us.vonzipper.com. But it might be a little expensive. I also see some von zipper sunglasses at framesdirect.com. It seems they are cheaper than they were at vonzipper.com. Anyway, to be sure, i think you'd better choose it at vonzipper.com. Good luck.
The von zipper sunglasses are usually made in America. They are designed in fashionable appearance. And their material so durable that you can wear at least three years. They are worthy to be worn. You can buy one online with the relatively cheap price. Just from the brand, manual work and the details can you find whether it is real.
They currently manufacture shades in China AND Italy. Models have been moving to China over the last couple years.In general, and particularly for my model (Skitch), the Chinese version is higher quality.Since I was expecting the Chinese version and I got the Italian one, they are happy to fullfill a warranty claim and replace my Italian made Skitchs with Chinese ones.
