The Layla red wine glasses are superior in quality. I love the authentic crystal from Europe and the very classy look of these wine glasses. They are not only elegant in design but are super light when lifted. They hold about 16oz (500ml) of red wine. This works very well with my in home bar collection and my guests were commenting all over. I tried different red wines in these glasses and the color of the wine is perfect along with the crystal sound it makes when you rub the top of the glass slowly. These are dishwasher safe but I opt to hand wash these. They are very durable and are made from quality materials. They have very stable flat foot. Perfect gift for the holidays, as a house warming gift, or special gift for someone who adores wine. Excellent product that should serve for years to come.
