Six Christmas Teacup and saucer - Christmas pleasures kopin desin set of 6

This is a set of teacup and saucer with KOPIN Christmas pleasures design. These are a replica as the stamp at the bottom says ARTCON since 1990. In excellent condition. I have a mix of these in my Kopin collection. And its hard to tell the difference. In my opinion they are not porcelain like the originals. Set of 6
