Alpine Cuisine Fine Porcelain 10pc Teacup and Saucer Set

Approx 3oz teacups, just enough for an espresso shot. Set comes with 10 teacups and 10 saucers. Some minor defects. 1 of the saucers has a chip and 1 of the teacups has a chip. There are also some dark marks in 1 of the teacups. I have tried to scrub with soap, water and even alchohol, it doesn't come off. Overall majority of the cups and saucers are in good condition.
