This is a ceramic shot glass, likely from the Lipari series, made by the Italian Sicilian brand Ceramiche de Simone. It is completely handmade and hand-painted by artisans, known for its vibrant colors that brighten up the dining table. I received this as a souvenir, but I don't drink limoncello, liqueurs, or espresso at home, so I'm selling it to declutter. The stain-like marks on the inside are likely paint imperfections from the original production; please check the photos. Size (approximate, measured by hand): Height: Approximately 6.3cm Diameter: 5.4cm Please refrain from purchasing if you are sensitive to used items. Thank you for looking.
