GuinnessCeramic White Espresso Mug with Toucan Label Design

I thought I was buying a coffee cup, of approximately the 6-8 ounce size. The Amazon site description says the capacity is 500 ml - that is over 16 ounces. I thought that was a mistake but ordered it to be sure.When I received the cup, I realized this is meant to hold literally one shot of espresso. The capacity is maybe 50 ml. In the physical description of the cup, it says it is 5.5 cm tall - that's just over 2 inches tall!While I really like the design and pictures on the cup, I don't need a single espresso cup size.
