Alas, I can't say anything about glasses. In two months the parcel did not arrive in my country. It is a pity, but I think it's not the fault of the seller, his work he did perfectly, quickly (processing the order, sending). After the opening of the dispute agreed immediately. So 5 stars is a store, not a product, alas.
These are perfect glasses for such a price. At a discount of 11.11 took for 524 rubles. Very high quality plastic. Obscure perfectly. Packed into a double box in the package. In the kit there is a bag black on a lace of fabric, a bag of dense leather Zama and a napkin for rubbing glasses. Strange thing: in glasses the phone screen turns rainbow)). Seller recommend. Delivery was 3 weeks before St. Petersburg. By the way, Pts dense arches, but do not press. I hope so de tight and will remain to sit
