Review on 170mL Stainless Espresso Approved Recaps by Steven Loy

The dimensions given for a 170ml cup (2.4 or 2 and 3/8 inches) are actually 80ml cup sizes. I made a purchase based on the wrong sizes in the listing and the cups do not fit my espresso machine as intended. Note that the 170ml mug is 3 1/8 inches tall. So be sure to buy an 80ml mug if you want a short espresso cup, regardless of what the description or FAQ says.
