"The Expresso cup that could"
Color: 01_ Silver 1pc
This little espresso cup is perfect in all ways. The stainless steel is great if you happen to drop it on the floor. Nice and shiny with a touch of elegance, it just brings a smile to your face. Great little cup for my espresso!

Works well, measurement markings holding up
Color: 01_ Silver 1pc
This is a nice espresso shot cup. It's wide enough to catch both espresso streams coming down from the portafilter. I really like the measurement markings on the inside. I was concerned when I bought it that the markings might come off over time. I've had it for several months, and so far the marking are holding up well even when run through the dishwasher.
