This is a "replica" of a chicken cup, one of only seven in the world, made during the Ming Dynasty. It is 6 cm in diameter and 3 cm high. It comes in a set of 2. The original chicken cup is a historical artifact, and when it was auctioned in the past, one was sold for about 200 million yen. It is a good item for everyday use, such as for tea, or for display as a collection. It is new and unused, with no scratches or stains. To reiterate, it is a replica.
