These days, there are a lot of options when it comes to reusable coffee cups. You can get ones that will hold a single cup and you can get ones big enough to pour the entire pot into. Be aware that the large mug may be heavy and you may be more prone to drop it! Regardless, no matter what size you want, you should easily be able to find one. They come in a wide variety of colours these days so you can easily find out that reflects your personality, such as one that indicates not to talk to you until the mug is almost empty or that you are grumpy in the morning until you have ingested your morning dose of coffee. As with anything that is reusable, you can put any number of beverages into it or you could use it to keep food hot for a while.
