The cups themselves are not perfect: uneven glaze, some with inclusions or paint chips. Not all cups, Abeer some.
Nevertheless, 3 stars, because for 2.99 EUR, which had cost the cups, probably not have been expected. Maybe it was even a price error (now cost 7.99), and who simply sent out the B-Ware. But that's just speculation.
Conclusion: if the less than 5 EUR, then you can strike without hesitation.
