These tumblers are fantastic. You can use them for more than wine. I tried putting coffee in one and the tumbler kept it hot! This set came with extra seals for the lid and metal straws! The tumblers are crafted well and keep contents very cold/warm depending on what you are using it for. Toss a few ice cubes in and they stay frozen for HOURS! I am very happy with them. May purchase another set for a gift!
