Using this wine cup is super easy. Just open the sliding shatter - proof lid and pour in your favorite wine. It's great for both white and red wines. Remember, it can keep your drink cool for over 9 hours and hot for 3 hours, so you don't have to worry about your wine getting warm quickly. When it comes to cleaning, you can use mild dish soap and warm water. Don't use abrasive cleaners as they might scratch the stainless - steel surface. Also, make sure to dry it thoroughly before storing it. The silicone bottom helps keep it in place, so try not to damage it. That's all you need to know to enjoy your wine with this amazing cup!
