Is there a way to make my own reusable coffee cup?
assistant
Yes, there is! You can make your own reusable coffee cup by using an insulated mug or thermos. Make sure the container you choose is made of BPA-free plastic and has a lid that seals tightly. To use it, simply fill it with hot water before you head out in the morning, then take it with you when you go to work. When you get home, just pour out the hot water and add cold water for your coffee.
