These 4 oz espresso cups hold a single or double espresso. They are easy to hold with finger grooves and a beautiful transparent teal and green glaze on speckled clay. Similar to the opal espresso cup but with deeper hues of colour. Dishwasher and microwave safe. All of my work is handmade by myself. Small inconsistencies in colour, size and shape should be expected due to the nature of the process. Price is per mug(Cup)
