Using these cups is super easy. Just take one out of the pack and fill it with your favorite beverage. They're great for parties and events, so you don't have to worry about washing up. But remember, don't put them in the microwave or dishwasher as they're not safe for that. After use, if you want to be eco - friendly, you can recycle them. Store them in a dry place to keep them in good condition. That's all there is to it!
