16 oz ceramic travel mugs are a great size.
It is large enough that you can get a good amount of tea or any drink in it, but not so large that it would never work for coffee, if you like it black. It’s also not so large that your drink cools down long before you get a chance to finish it.
All of these tumblers come with a cover, making them great for the road. The tops prevent splashing and spilling, which is important when you’re on the go.
Some have handles and some do not. It is down to personal preference, whether you need one. But you do want to make sure the handle is located high enough up the cup that you can still put the cup in a car cup holder.
The designs vary greatly, so there is sure to be something for anyone who wants a tumbler to enjoy their drink while on the go. The one thing they all have in common is the size. And this size is arguably the most versatile and useful.
