They keep the drink hot/cold for a while
Made from BPA-free food-grade stainless steel, the vacuum insulated tumbler has double walls and is perfect for keeping wine cool for up to 12 hours. If you are a wine lover, this glass can also keep you warm for a long time (at the ideal temperature).
What's more, the glasses have a splash-proof slide lid that can be replaced as needed. In addition, this stylish and insulated glass can hold about half a bottle at a time, making it easier to use. In other words, they are large enough to store about 400ml of wine.
They don't just store wine
Coffee, tea, soups, smoothies, frozen yogurt, and stews are just a few of the many items you can store in these insulating solutions. When it comes to hot drinks and food, these glasses can keep them warm/cool for up to 6 hours. Amazing, right? This makes them perfect for camping, hiking, and even "to go" smoothies for breakfast. You can also prepare a pre-workout protein shake and store it in this insulator until you're ready to drink.
