Actually I wanted to give the glasses for Christmas. However, four glasses, two inside with scratches (probably due to manufacturing) and a glass has moreover even at the edge of an open bubble. Quality control does not exist unfortunately appear. A replacement is not possible because Amazon has the goods shipped only and a new order (hoping to get proper glasses), I no longer see a since about the lack of quality, the price per glass of 9.90 EUR for my order task and obtaining package has been increased by 50% in the price of 14.90 EUR !!!!!!
