Espresso mugs. Red coffee cups. 16 pieces

The cups haven't been used. Judging by the appearance, they seem to be ceramic, but I'm not a specialist. The edges are black, both on the plates and the cups. From the factory, some dishes have black edges that aren't perfectly drawn. I can send additional pictures. 😊 Selling all together, 16 pieces, or in sets of 8 pieces.
