A funny ceramic travel mug is great, because it usually gets a chuckle out of people. And who couldn’t use a laugh first thing in the morning?
Porcelain cups do a good job of insulating, especially if they are double walled. Metal is better, but porcelain does not impart a flavor on your drink, so that is a huge advantage. Porcelain tumblers are usually cheaper as well, but they do break more easily.
All these cups come with a lid, usually made from plastic or silicone. These help keep in the heat and also prevent splashing. Some seal tightly to prevent spilling, too.
I love a humorous quote or saying and think a coffee or tea cup is the perfect spot for one. These ones below are varied, so there should be something that appeals to anyone. Even if none of the humor is your thing, you’ll find plenty more options on Amazon.
