The espresso machine accessory has a 4 oz. capacity that allows you to fill 2-servings of espresso at one time. Its double spouts make pouring more convenient and less likely to leak, so the glass espresso cup pours smoothly without staining the tabletop, making it a good helper for your coffee. Made of premium clear, thick-walled, borosilicate heat-resistant glass, it does not contain lead or chromium and can be in direct contact with food. The cup is microwave safe and dishwasher safe, making it super easy to clean with a simple hand wash or by placing it in the dishwasher. Its crystal clear appearance features smooth and delicate lines with a good hand feeling. This espresso cup is perfect for a wide variety of uses including espresso, milk, milk froth, smoothies, desserts, salad dressing, butter, tomato sauce, and more.
